It's not harder, though, it's actually quite instant if you know what you're doing. A lot of documentation is literally one single web page, and the majority that is not can be navigated with the regular search and ctrl+F just fine.

There's no substitute to taking 40 minutes to get acquainted with the documentation to know what you need rather than trial & error your way through a problem blindly.

you could get an LLM to return you the correct page in some documentation

It's unreliable and prone to errors, and I say that after using LLM-based searches for months at work. Too many times it confuses areas, makes stuff up, or cites some irrelevant page just to give any answer at all.
