Instead you have legal concerns when you are re-licensing code you don't know where it comes from.

Someone could have published a snippet of code with retained copyright (not FOSS) and GPT-4 slurped it up, splitting it back to you and somehow the law firm representing the author comes across it.

Have there been any tried cases of this happening yet, or is everyone still waiting for the legal precedent to be set for this situation?

This sounds like plausible deniability, and not legal problems, at the hobbiest level. Not something I am going to worry about.
