For really basic overviews of different technologies I've found YouTube videos to be useful.

For code examples I've always found GitHub code search to be super useful.

I haven't really found a use case for LLMs where it's any faster than the research tools already available on the internet.

A good example is writing AWS CDK code, which is a pain in the ass. But there are so many examples to pull from on GitHub code search that are being used in real projects that I've found this method to be faster than prompting an LLM that may or may not be correct.
