> a blatantly derived work only using 50% of a copyrighted work without permission

What's the work here? If it's the output of the LLM, you have to feed in the entire book to make it output half a book so on an ethical level I'd say it's not an issue. If you start with a few sentences, you'll get back less than you put in.

If the work is the LLM itself, something you don't distribute is much less affected by copyright. Go ahead and play entire songs by other artists during your jam sessions.
