I was shopping for a new clothes washer, and was strongly considering an LG until I saw it had “AI wash”. I can see relevance for AI in some places, but washing clothes is NOT one of them.

I might be thinking the same. But I actually purchased an LG washer a couple months ago and finally got around to finding and reading the manual, and realized that I should have been doing "AI wash" instead of the "normal wash" that I always did.

The manual says that this is what "AI wash" actually is for:

"This cycle automatically adjusts wash and rinse patterns based on load size".
