I think you're exaggerating. There are several ways an LLM can discern the applicability of certain data to a context (document metadata such as TLD, cross check with applicable authoritative codes and regulations, be wary of random forum posts.)

I'm pretty sure an LLM can provide pretty refined answers given some reasonable context. i.e. I want to rewire a socked in my apartment, which is in London, UK. What do I need to do?
