I like to do the opposite, asking the LLM to give me relevant follow-up documentation, like the actually docs, where I can read and understand things myself. Data structures, techniques, etc. I still like to read that from the authors, much easier and trustworthy to grasp.

I do this too. LLMs are amazing at finding weird trivia deep in the docs. But you have to go check the original. The machine is often correct-ish.
