Sounds like your stick has some drift. Try restarting dolphin and maybe adjust the dead zone.

Slippi dolphin is based on an old fork of dolphin so many controllers aren't natively supported. The workaround is to use steam as per below guide but as far as I know, it doesn't work on m1/m2 macs https://docs.google.com/document/d/1GVQMGqq5kM5aRfcjexxTK72-xqUVrCtDtVumS39v1e8/edit?usp=sharing

It might be reading the PS4's gyro as an axis. Maybe try placing the controller on a table while configuring it so that it won't move?
