> there's no way to check out an ebook from a library in a way that doesn't involve Amazon

Isn't this what Libby - https://libbyapp.com/ - does?

I use overdrive from my kobo. I have three library cards in it, unfortunately I can't use them three at the same time so depending on what kind of book I want, I switch accounts. I can search, reserve, and borrow from any of those consortiums directly from the Kobo device.

But then you can't use it on an e-reader. It remains in the app.

Libby (and by extension Overdrive) supports checking out books onto supported e-readers. They must support either the Kindle or Adobe DRM standards though.
