This sounds a lot like the legal wranglings of “Jackass Hill” near Columbia Airport (O22). Residents constantly complain about aircraft “buzzing” their homes (which were built long after the airport so the airport didn’t just sneak up on them). A lot of weekend pilots fly there and aren’t expecting the density altitude in summer and do take a little longer gain altitude.
Or the woman near my home airport (LOCID redacted) who claimed that the airport beacon was causing her horses to stampede when it came on in the evening. Can two horses create a stampede? 
I hope both parties in this lawsuit get the help they need.
