Saw it on a package for a water pump that it shouldn’t be run dry for more than 1 second. If air is going through it, which requires less energy to move than water, then it should be no big deal, right?

Pressure. Air compresses at a different rate than water, so when a pump designed for water gets an air bubble in the line or pump that pressure differential can damage internal working of the pump.
