orion can send a normal macos notification saying "low power mode turned on/off", to notify the user, maybe with a description saying "batter percentage is low" or "device was plugged in"
the option set in settings should be used as the baseline option, and then further configured through user's manual setting
so, if the user wants to change the setting to what orion isn't supposed to be (as defined in the settings), warn the user if they try to turn it on/off when it shouldn't be, then do what the user wants to do. revert to normal settings next time orion starts, or if an event like plug/unplug affects it
