Regarding the idea that YHWH was present in some copies of the Greek Septuagint (and/or other Greek translations of the Hebrew Scriptures OT) in time of the influential theologian named Origen, the WT correctly said that Origin said he had seen the name in some copies of the Septuagint and the best (most accurate) copies of the Septuagint contained the name. Note that https://en.wikipedia.org/wiki/Tetragrammaton confirms this by saying the following.
'Origen (Commentary on Psalms
2.2) said that in the most accurate manuscripts the name was written in
an older form of the Hebrew characters, the paleo-Hebrew letters, not
the square: "In the more accurate exemplars the (divine) name is written
in Hebrew characters; not, however, in the current script, but in the
most ancient." While Pietersma interprets this statement as referring to
the Septuagint,[79] Wilkinson says one might assume that Origen refers specifically to the version of Aquila of Sinope, which follows the Hebrew text very closely, but he may perhaps refer to Greek versions in general.[94]

https://en.wikipedia.org/wiki/Origen says Origen of Alexandria was a Christian scholar who lived from c. 185 – c. 253. It also says the following. "... Origen was a subordinationist,[207][206][208][209] meaning he believed that the Father was superior to the Son and the Son was superior to the Holy Spirit .... At one point Origen suggests that the Son was created by the Father .... At the time when Origen was alive, orthodox views on the Trinity had not yet been formulated[216][219] and subordinationism was not yet considered heretical.[216][219] In fact, virtually all orthodox theologians prior to the Arian controversy in the latter half of the fourth century were subordinationists to some extent.[219] ... Origen is often seen as the first major Christian theologian.[221] ... Origen deeply influenced Arius of Alexandria and later followers of Arianism.[234][220][235][236] Although the extent of the relationship between the two is debated,[237] in antiquity, many orthodox Christians believed that Origen was the true and ultimate source of the Arian heresy.[237][238] "
Note that at a time, during the later 2nd century CE to the early (and possibly the mid) 3rd century CE, when some copies of the Greek Septuagint were known to have the Name (YHWH) in Hebrew script, it was not yet considered heretical for a Christian to believe that God the Father was superior to Jesus Christ and that Jesus Christ was created by God the Father. When Origen wrote, perhaps some copies of the NT then in still existence had the name YHWH in it and perhaps Origen knew of such. Also note that Origen's writings influenced Arius and that Arius' writings for a period time influenced a great many Christians to believing in Arianism. The WT, in regards to the idea of whether or not Christ is God (or a god), believes in Arianism. Though Arianism is now often considered a heresy, for period of time it was widely believed in Christianity. See https://en.wikipedia.org/wiki/Arianism . It says the following.
'Arianism (Koinē Greek: Ἀρειανισμός, Areianismós)[1] is a Christological doctrine first attributed to Arius (c. AD 256–336),[1][2][3] a Christian presbyter from Alexandria, Egypt.[1] Arian theology holds that Jesus Christ is the Son of God,[4][a][5][b] who was begotten by God the Father[2]
with the difference that the Son of God did not always exist but was
begotten within time by God the Father, therefore Jesus was not
co-eternal with God the Father.[2]
Arius' trinitarian theology, later given an extreme form by
Aetius and his disciple
Eunomius and called
anomoean ("dissimilar"), asserts a total dissimilarity between the Son and the Father.
[6] Arianism holds that the Son is distinct from the Father and therefore subordinate to him.
[3] '
Regarding how widespread that teaching was for a period of time, note that the same article says the following.
" Controversy over Arianism
arose in the late 3rd century and persisted throughout most of the 4th
century. It involved most church members—from simple believers, priests,
and monks to bishops, emperors, and members of Rome's imperial family.
Two Roman emperors, Constantius II and Valens, became Arians or Semi-Arians, as did prominent Gothic, Vandal, and Lombard warlords both before and after the fall of the Western Roman Empire. Such a deep controversy within the early Church
during this period of its development could not have materialized
without significant historical influences providing a basis for the
Arian doctrines.[13] "
In our time period (1800 to the present year) it is common for authors to revised their books and publishers to produce those revised editions. It is also common for publishers to revise books after copyrights have expired and after the authors have died. it thus shouldn't be surprising that some early Christians in many copies of the NT made some revisions to it, to suit their purposes. They might have felt they were justified to use the word Kyrios in place of the the Hebrew characters of "YHWH" to avoid confusion to Greek records and out of reverence they might have been afraid to attempt to transliterate the Hebrew letters of "YHWH" into Greek letters. Furthermore since some erroneous (due to copyist errors) of Greek transliterations of YHWH in the Septuagint into Greek as PIPI (something which does not mean YHWH, but which looks a lot like the Hebrew letters of "YHWH"), they might have decided it was best to translate it as "Lord" instead. There also existed variant transliterations of YHWH into Greek letters and the Christian copyists of the NT might have thus decided to standardize on the word "Lord" to avoid confusion and to provide consistency.
