TUI already has a far more established technical meaning. From www.yourdictionary.com:

TUI =

(Telephone User Interface) The combination of Touch-tone input from the telephone keypad coupled with speech output from the connected voicemail or IVR application. While early speech technology was struggling to recognize voice utterances for voice control and data entry, the ubiquitous Touch-tone keypad was a practical solution. It works with enterprise telephone networks, the PSTN, public payphones and traditional cellphones. Its centerpiece is the standard 12-key keypad and conventions such as using the pound key for "enter," the star key for "up one level" or "escape," and "1" for yes, "2" for no.

Using this abbreviation for new uses can only reduce readability.

Yes, there is a more established term for TUI, yet it’s not what you thought it is. TUI for terminal user interface is not so new and not so obscure as you make it sound (especially in the data science, ipython, Julia, etc. Community).

I think as it‘s an expert Interface the abbreviation is not such a big problem. Yet, I agree it‘s always good to give the full term before using an abbreviation.

I still remember the color order for the wires on a DS1 crossover cable and even I know that "TUI" means "text UI".
