Advertisers pay and it's reasonable from financial perspective for Google to turn a blind eye before any complaints.

Their main business is ads, not search.

I guess it's too bad that having a purely financial perspective just isn't reasonable in most cases. I don't understand why people think that's a good excuse to harm and endanger lives, what a wild take

They find phone numbers for places if you are specific enough. If you search, phone number for restaurant, you get a list of restaurants. Google isn't employing someone to curate that list.

Actually, if I google "phone number ambulance" in America, I get a bunch of random ambulance companies and not 911.

If I just google "ambulance" I get stuff about the recent movie.
