The toggle walls, squares with a green outline toggle off and on when the green button is pushed. All walls on the level toggle when any green button is pushed. This can be represented in a classical system by having a boolean literal specifying the which state the toggled walls are in and switching it when ever the green button is pushed. This literal would then be part of the precondition for stepping onto a toggle wall.
