I can't say I fully understand how LLMs work (can't anyone??) but I know a little and your comment doesn't seem to understand how they use training data. They don't use their training data to "memorize" sentences, they use it as an example (among billions) of how language works. It's still just an analogy, but it really is pretty close to LLMs "learning" a language by seeing it used over and over. Keeping in mind that we're still in an analogy, it isn't considered "derivative" when someone learns a language from examples of that language and then goes on to write a poem in that language.

Copyright doesn't even apply, except perhaps on extremely fringe cases. If a journalist put their article up online for general consumption, then it doesn't violate copyright to use that work as a way to train a LLM on what the language looks like when used properly. There is no aspect of copyright law that covers this, but I don't see why it would be any different than the human equivalent. Would you really back up the NYT if they claimed that using their articles to learn English was in violation of their copyright? Do people need to attribute where they learned a new word or strengthened their understanding of a language if they answer a question using that word? Does that even make sense?
