Quotation is fair use in all sensible copyright system. An LLM will mostly be able to quote anything, and should be. Quotation is not derived work. LLMs are not stealing copyrighted work. They just show that Harry Potter is in English and a mostly logical story. If someone is stabbed, they will die in most stories, that's not copyrightable. If you have an engine that knows everything, it will be able to quote everything.
