This is pretty spot on. I tried something similar a while back and found that the typing latency was on the order of ~120 ms which made it feel mushy and led to a lot of errors. The need to rethink graphics to handle refreshes should not be underestimated. A lot of UI patterns (almost all animations and transitions) rely on a period refresh rate. In order to make a compelling experience you need to rework a good bit of the UI.

You'd just need to adjust to typing "by feel", without needing that instant feedback from the screen. A typewriter or teletype also has inherently high "latency", so this fits quite well with that whole "e-paper" approach.

Could work like an electric typewriter. Keep the little LCD for the current line (or maybe 3-5) and let the E-ink be your “paper”.

Yeah, this is the best workaround. It is still slower and more error prone than typing on a standard LCD screen. Also, the benefit of an eInk reader is that it is easier to look at - not looking at the display sort of defeats the whole purpose.
