The real (legal) question in either case, is how much is actually copied, and how obvious is it.

It’s also incredibly hard to tell if a LLM copied something since you can’t ask it in court and it probably can’t even tell you if it did.
But the issue with copyright I think comes from the distribution of a (potentially derivative or transformative in the legal sense) work, which I would say is typically done manually by a human to some extent, so I think they would be on the hook for any potential violations in that case, possibly even if they cannot actually produce sources themselves since it was LLM-generated.
But the legal test always seems to come back to what I said before, simply "how much was copied, and how obvious is it?" which is going to be up to the subjective interpretation of each judge of every case.
