I do the same thing I think, but with Hammerspoon. The script I’m using in Hammerspoon automatically switches the Input Device back to Internal Microphone when a BT device is connected. Solves the issue for all BT devices w/speakers + mic. I haven’t used it, but I’m guessing ToothFairy does the same thing, although maybe it has some more bells and whistles.
