Realize the inspectors have varying backgrounds. Some are more versed on electronics than others. The main function of the inspectors is to make sure your robot is relatively safe and meets the rules.

Is it legal just to use an NPN transistor to drive the LED strip? drive the transistor from the DIO on the roborio. power form a fused output on PDB.

That would be a custom circuit. As long as it meets the rules for custom circuits, it is legal.
