The Dumbphone 2 listed is a TCL Flip 2 which runs modified AOSP. Functionally, the Flip 2 is a dumbphone, though if you’re willing to put in the elbow grease you can install apps through adb and install a cursor to use them. The screen resolution and modified OS make many apps unusable though, but I was able to get Firefox, Jerboa, and Molly (Signal) working on mine. It was definitely better to tether to a tablet or laptop as you said.
I think the Sunbeam phones, Keyphone, and Light phone are AOSP as well, with varying openness.
A lot of manufacturers just use gutted AOSP so they don’t have to write network, UI, notification, etc. stacks from scratch. If not Android it’s usually Mocor or KaiOS
