Sure; say someone comes up with a great proverb in their book, or a nice phrase, and it catches on. People don't have to cite where it came from in order to use it. What if someone copies a half page paragraph? They are in a gray area where it will likely be in their favor if they can avoid the accusation of plagiarism, if they intend to use a fair use defense. Anyway, the organizations behind popular LLMS are perpetrating massive copyright infringement and plagiarism. A fair use defense is rationally not possible. Firstly, to claim fair use while you are making commercial use of the material is going to be difficult right off the bat. Fair use claims are bolstered by non-commercial use. Small size of excerpts favors fair use claims. Can't do that here. Transformative use? Not really; LLMs spit out the information verbatim if prompted in the right ways. Exploitative uses will probably not be viewed as transformative by the court.
