That generally only happens in cases of overfitting, where the model was trained on a poorly de-duplicated data set that contains many copies of that book (or excerpts, quotes, and so forth). This is considered a flaw by AI trainers and a lot of work goes into sanitizing the training data to prevent it.
Licensing only works as well as enforcing it. How do you show a LLM consumed your code as part of its training data?
Some authors typed the first few sentences of their book and the LLM spit out the rest.
