That depends... In the path, I suppose, they would move it. If there was an event, there usually is a NOTAMS for pilots to avoid flyovers or at least to look out for said lazer displays to beware of such, but. As far as sopping them, I would think of any those in direct flightpaths, but than again, I am not aware of any specific shows or venues that are no longer allowed to run shows because of inline flightpath location/disruption.
I think most large shows are known by local ATC anyways, and the disturbances are just punks....
