Curious as to how much water is needed for irrigation for the typical lawn
in terms of inches in the typical growing season, this includes rain as well
in my question?


That depends on the type of grass and the climate. Some grasses are
more thirsty than others. My low-humidity climate results in more loss
through evaporation than would happen in Louisiana or Florida.

It might also depend on the length of the growing season. With a short
growing season, a lawn will be dormant (or at least semi-dormant)
longer, during which it requires less water.
