How are you getting GPIO?

Most likely he doesn't use GPIO, if it's just a tailscale/pihole client.

If you really need GPIO then add a USB-C OTG MCU board like a ESP32, or even the ancient Arduino works via USB and serial TTY on Android.

Several methods. You can run a MQTT server, Lightweight HTTP Server or even just serial over USB. Literally the world is your oyster. Extra special points if you do HTTP over ethernet

Flash the MCU with a program that takes a text protocol over the UART from the host and uses it to control its GPIOs

Use something like this:

Adafruit FT232H Breakout - General Purpose USB to GPIO, SPI, I2C https://www.adafruit.com/product/2264

(or even more cheaply a CH347T board which are dirt cheap on Aliexpress)

Both have decent Python support.
