Modern EVs with thermal management simply haven't been around for long enough for a significant quantity to reach 1 million miles, especially those with LFP cells.

There are some taxis and limo service Teslas that famously did make it to 300-400k+ miles on their original pack.

The technology exists, CATL is offering a million-mile/15 year warranty for some of their packs: https://chargedevs.com/newswire/catl-warrants-its-new-ev-bat...

It's a solved problem. When you consider TCO, EVs win even if the battery needs replacement.
