I don't think that the "invention" of Jesus has been documented.
The use of the Old Testament as prophecies foreseeing the arrival of Jesus Christ is evident. Nobody denies it. You can amass a mountain of quotations. Now then the problem is whether these are used as an invention of a semi-god like a man or as a justification/deification of a man.
I have not seen any commentary/litany of yours that have addressed this issue correctly.
Your claim that you "have not seen any commentary/litany" that "have addressed this issue correctly" is really irrelevant [baseless rhetoric] since your statement may be false.
The use of so-called prophecies in the Old Testament is indeed evidence that the character called Jesus of Nazareth was manufactured.
Your question or problem has zero negative effect on the argument that Jesus of the NT was a character of fiction as described in Christian writings.
Once it is realised that there is no historical contemporary evidence of Jesus, Paul, Peter/Cephas, James and all so-called relatives and apostles of Jesus then it can be argued for infinity that the Jesus stories found in the Gospels and Epistles were not historical accounts at any time.
The argument that Jesus, his apostles and relatives were figures of fiction cannot ever be overturned by anyone [Scholar or not] since all stories of Jesus are fiction, are dated no earlier than the 2nd century and not mentioned by any accepted contemporary historical sources.
The fiction characters [Jesus, his apostles and relatives] were invented no earlier than AFTER the Fall of the Jewish Temple c 70 CE and after the writings attributed to Josephus, Tacitus and Suetonius or no earlier than c 110 CE.
