See this, it has the T9 input method too:
https://github.com/dessalines/thumb-key
I see mention of T9 in "On phones that used the 9-key numeric layout, T9 predictive text was used. Other phones used the full-hand layout with the familiar QWERTY layout, with other proprietary predictive methods." I'm unable to verify this app has T9 as an input method. Is there a custom layout for this?
T9 was pretty sweet as you could type without needing to look at the device.
Maybe this layout?

AnySoftKeyboard has T9-like layout but lacks T9 prediction.
Yeah, these days I only type on the touch screen if it's absolutely unavoidable - if I can't get to my laptop, but can still sit down, I much prefer a little flip out Bluetooth keyboard with the phone on a stand.
