Pi 4 with Pi Touch Display was created by KenSea
I was typing up a post to ask for help getting LinuxCNC 2.9.2 running on a Raspberry Pi 4 B attached to a Raspberry Pi 7 inch Touch Display, when I finally figured out the solution. Thought I'd still make the post for helping others or possibly even future me if I have to rebuild this system one day.
The Pi Touch uses DSI for connecting to a Raspberry Pi and seems LinuxCNC doesn't have the required settings enabled in the config.txt by default. Not really a surprise as its probably an unusual pairing of hardware and OS.
The solution was adding the below text to config.txt

#DSI1 Use
dtoverlay=vc4-kms-dsi-7inch
# Automatically load overlays for detected DSI displays
display_auto_detect=1
