It's well-known books, yes, and even then with significant errors which means presumably lawyers for the AI companies would argue there is no possible damage. That said, US copright law has statutory damages for registered works that are not based on real, documented damages. I could totally see it being fought over, but I also agree it's probably not going to end up being game changing.

I suspect very works will be memorised enough to be an issue, and we'll see the providers tighten up their guardrails a bit for works that are well known enough to actually be a potential issue (issue in the form of lawsuits, not in the form of real damages to the copyright holders)
