Hi JT
always find the information here informative, but please read your sources.
The Mayo clinic article you referenced specifically says that there is no risk from domestic air conditioners of Legionaires disease.
Legionaires is associated with commercial air conditioning systems that use water to cool the chillers. The warm water provides a breeding ground for bacteria.
The condensate from a domestic air conditioner is no warmer than ambient air. In fact it’s cooler. ( read about dew points) It’s no worse than breathing in the air around you.
