If you go on blind and ask about interview processes the vast majority of high paying companies where TC is over $200k are going to ask LC questions. So I'd say yes, being able to solve LC gives you good odds for landing high-paying jobs. You can go on LC (I think it requires premium) and see people post similar things (may be biased there). There's an entire category in the problems where you can see what companies have asked certain Qs and their frequency (6 months, 1 year, 3 years, etc). I myself am starting the LC grind, the only thing I've honestly regretted in my career is not getting a CS degree (mine is in Maths). Never having a solid foundation in DSA makes LC prep painful, also the first time I'm prepping LC in general. I'm a frontend developer for the last 7ish years and it kinda sucks that I have to do LC to get these jobs. I know some companies are starting to give different tracts for frontend roles but the vast majority still seem to be LC problems.
