ChatGPT and LLMs work poorly when you want accuracy on something obscure, and work really well when you ask it how to do something that many people have done or are doing. Thing is, many people - probably the majority - work on just that. They aren't looking for answers to challenging issues like your question where 'Google searching hasn't yielded answers for', they are looking for answers to questions where google and stack overflow does have thousands of results for similar, potentially related scenarios, and want something to summarize or filter it into an usable answer, and ChatGPT provides that option. When the official documentation provides all the information in a poor format so you can't just search for the answer, ChatGPT can extract an answer from it. Not "some starting points for learning more about some well known topic" as you say, but rather some "digested, complete, specific result from a well known topic to avoid having to learn learning anything more than strictly necessary for the outcome".
