That is definitely the case/challenge. For example: I've recently been traveling in Brazil in non-mainstream locations (at least for US/EU travelers) - some of the places were on gMaps as open but in reality they were permanently closed or just online delivery businesses with no physical presence. gMaps were messed up and if you manually investigate it is very hard to figure out what is really going on. - Online: Really attentive human being might be able to figure it out after spending hours online (using Instagram that is strong in Brazil, forums, etc ). LLMs can potentially do the same job but cheaper/faster - Offline verification can definitely help, but the downside is that it usually costs $$$ -> you need to be smart/strategic what you verify offline.
