To begin...

This one's vague, but it does leave the potential for a ton of staffed temples scattered all over.

There's more to this than what you posted. Az'atta actually has few enduring and permanent temples. Her clergy is highly migratory, and will build temples where and when there is a need, but also move on and abandon them/tear them down when that need is passed. I actually ran a CDQ (which evolved into another CDQ) for someone seeking to find lost temples to Az'atta. They found one...and a defaced stone that was probably a shrine...and something completely undetermined that might have been a temple. Point is, the full context disagrees with your one sentence.

Taking the Toran example, there's no way that Toran would have a full-blown temple in every town, whether it's something on the order of Fort Llast or the Citadel in Huangjin. If a small town did have a temple, it might just be as simple as another house with an ankh on the door. Some places may have a simple shrine and maybe a priest in town...some places may not have a presence of Toran at all.

Speaking more generally, we're also bumping into a version problem, where what you are quoting is based on old lore and which has not really evolved to its proper accuracy. It's entirely possible, even likely, that the words "temple" and "shrine" were used somewhat interchangeably in the old lore. I think it's just an unfortunate ambiguity.

And also take into consideration that some deities may simply not be popular or desired in some locations. A large, generally lawful city like Port Hempsted probably won't have a "temple" to Corath, but it would be almost certain that someone had a "shrine" or altar somewhere, known only to the faithful. One might have to look really hard to find any traces of Aeridin in Arnax. Finding a temple or even a shrine to Lucinda in Brenuth would also be unlikely.
