"where" is the key word here I think. But at least in the vicinity of the major US coastal cities (SFBA, Seattle, NYC, probably LA and a few others) where a lot of tech jobs are concentrated, I would say most companies are in fact, leetcoding candidates to some degree.
Half my team is in London (big bank), as is my manager, and I know they leetcode candidates there too - and we're not even a tech company or elite financial firm, just a boring big conservative bank.
If you're looking for a job in this day and age, I think it's safer to assume you're going to get leetcoded and be prepared. Rather than try to find the rarer and rarer company that doesn't leetcode you.
