There should be no ambiguity here! A toggle button is an analogue for a physical switch. Unless the switch state is dependent on other switches, it must always display its current state. i.e. ENABLED is always true unless POWER is OFF.

There is ambiguity in the physical world. Some audio equipment have what's called a ground lift. It physically disconnects the ground conductor between two devices, and it's usually a single push-toggle in/out button. I've seen some devices with "Ground On/Off" - does that mean grounded (not lifted) or not grounded (lifted)? IIRC one of the DI boxes I've used is the opposite of what you'd expect - "Off" means lift is off, meaning ground loop is connected. The sensible devices have two states "Lift/Gnd".

That is a poor design choice. VERB STATE TRUE is standard for every toggle switch on all my hardware, including prosumer amps. Changing this can be deadly, and was found to be part of the reason for the 737 MAX going down in 2019:
