From what I seen, the leetcode is self reproducing dysfunction. There is whole subculture that believes being good at leetcode like tests and puzzles makes you inherently superior in all aspects, because you are smart. After all, they were good at leetcode like tests and are superior and smart. It is people who grew up in that subculture becoming managers recreating the culture they grew up in.

That is why the "not a valid measurement for actual performance in a dev job" thing does not matter. Too many people are emotionally invested in this being important measure. Their and their friends self worth is attached to it.
