Yep, you can. I tested by typing the first 13 words of the book Frankenstein and GPT3.5 happily completed the rest. Feel free to try.

When I ask it for anything from Game of Thrones it refuses beyond offering a summary.

How are you going to codify that? "You can't feed my text into an algorithm that has the ability to reproduce it"?
I think for a few high-profile authors (for books like Harry Potter and Game of Thrones), OpenAI probably installed some output filters in order to not get sued too hard. Of course, I can't definitively check that without access to the raw model. Which OpenAI conveniently doesn't provide.
