Thats a bit of a myth, most diseases and weeds etc can be controlled by
cultural practices. Furthermore, amenity ground comes under much
stricter control than agriculture and horticulture.

That's true. and some places do this, and at least in my experience,
you will always get a few weeds on the greens, which is a good sign,
IMHO. I wonder if they teach this in the greenskeepers programs in US
universities?

One thing I have also seen is the herbicides damage the soil
ecosystem, resulting in algal and fungal outbreaks attacking the
greens as a result, for which they use even more chemicals.

Had a neighbour who used a company called chemlawn to keep his lawn.
Beautiful green lawn. Sold the house and the new owner didn't keep up
the chemlawn. Totally dead lawn within a year, and needed to resod.
