So, when you look to Luke 1.1 as evidence of a tradition grounded on eyewitness testimony, you are arguably relying on
(* the reference to unnamed but presumed folk - people he does not even claim to have met - who were presumably "eyewitnesses and servants of the word" seems exceedingly poor evidence.)
- an anonymous Gentile author
- writing primarily to a Gentile audience
- decades after the storied life of Jesus,
- an apologist who is making an ambiguous claim*
- in a verse that some believe to be a later anti-Marcionite addition.
There are always going to be arguments of the late writing and alternative authorship. And the opinions of people opposed to the traditions of the Church will always be picked up on by others opposed to those traditions and used as if they were facts.
Iranaeus of Lyons and the Muratorian Canon seem late attestations to the authorship of the gospels but there were plenty of quotes from writings earlier than that, which show what New Testament books were known and used.

So there is plenty of evidence of an early writing for Luke's gospel and there is plenty of internal evidence for the authorship of Luke.
Was it necessary for the early Christians, who probably knew the authors, to add an attestation to that at the start of the gospels. It seems it could have become necessary in the latter half of the 2nd century before that knowledge died out.
