Through what presently-existing technology, exactly, is this idea supposed to work over distances greater than at best a couple of miles with say LoRA?

I'm not equipped to analyse their claims in detail, but Apple claims the design of their find-my network is end-to-end encrypted, and presumably it would be a huge scandal if this turned out to be a massive lie.
It is end-to-end encrypted, yes. The protocol has been widely reverse-engineered and Apple can't actually read your item's location at all. It's pretty clever.
