This might be true if there is existing live mold somewhere in the toilet (for that, monthly tank bleach tablet) but otherwise a lid prevents spores from settling in the first place.
Humidity reduction by ventilation can slow/delay mold but only eradication stops it.
Well they’re on a well with a septic tank which means no chlorine in the water and they wouldn’t want put a bleach tab in because of the septic. But I agree it would be good to eradicate it if possible.
