There's a few variations of really cheap 8051 MCUs with USB support. https://hackaday.com/tag/ch554/

Are these ch554 family parts available in bulk? I don’t find them on mouser or Digikey for example.

The manufacturer appears to support direct purchase: http://www.wch-ic.com/services/buy_process.html

LCSC is another option: https://lcsc.com/products/Microcontroller-Units-MCUs-MPUs-SO...

You can find them on lcsc.
