An LLM answer is not "better", it's in a completely different category. LLM answers can be useful, for topics where you can easily verify a fact (i.e if you ask for a Linux command and it gives you one, you can run it and see if it did what you wanted), or for topics which are more opinion than pure fact ("list some trade-offs between decision A and decision B"). But when you want information that's provided by some authoritative source, you want to see it from that source.

Google Search has been terrible for a long time. But you could still dig through it and find those primary sources. That is, in my opinion, the primary purpose of a search engine. Replacing it with what an LLM has invented based on ingesting both reliable and unreliable sources is not viable for a large category of things. The main way we can judge the reliability of something is to loo at where it comes from. If I'm looking for, say, official US job market statistics, whether I trust the numbers I find depends on whether I find them published on a US government website or on a random person's blog. A number presented to me by a chat bot would not let me judge, so it's useless.

The best a language model could possibly do, by definition, is to find websites and link them to me, letting me judge their credibility. But then it's just a worse search engine.
