Why even use a LLM, just buy a cookbook and you can even waste less time and know the information is valid. And again if your logic is consistent, google routes your search to an LLM automatically and renders the reply - that will save as much time and do the same thing since LLMs are so good at parsing and presenting information. So why should I pick an LLM over google's inbuilt LLM or an actual cookbook on the desk? What wasted time is the LLM saving?
