https://github.com/ekmett/hide takes on that part of the project (formerly thc-edit mentioned in a couple of other replies). Not Turbo Vision based per se, but has that same classic style of UI. It renders itself via terminal, metal, vulkan or webgl UI and provides editor services, AI agent support, autocomplete, and can connect to another instance over SSH to provide these presentation services over the network.

Text is presented in a faux IBM VGA font, blue background, and in any of the non-terminal choices a subtle CRT grading/vignetting is applied if desired, but it is extended to full unicode including emoji with an optional stylization pass to make them feel more like the period editor experience. You can even switch display modes because most of the time I used Borland tools in my youth I'd run them in 80x50 mode.

My general intent is that the final installer will package both of them, just like Turbo Pascal bundled TP and TPC or Turbo C bundled TC and TCC.
