This should be handled more gracefully, but may I ask why you even want to call operator_menu_enum with BoolProperty ?

I'm probably just fishing around as there's not useful documentation or example how to set a BoolProperty through a menu item item (want a checkbox!) either in the API docs nor in blender.stackexchange, so this aging Java programmer is a tad lost.

You can set the (bool) property:

when executing via a popup dialog, see https://docs.blender.org/api/current/bpy.types.Operator.html#dialog-box
let the operator execute with the property set, something like layout.operator("XXX").myProp = True, so you could have two operator buttons (one with True, the other with False)

If you want to see a checkbox, probably go with the fist one (the dialog)
