All dough is highly processed. Milling, separation, other processes applies to the original plant product to make flour, then fermentation usually with highly refined sugar.
That depends on what you mean by processed. By your definition even milling your own flour is "processed". Places that make their own dough are far from the classic definition of processed.
you know the "processed" in "processed foods" doesn't mean milling grains, right? It's processes like freeze-drying, adding preservatives and various chemical agents to provide consistency, taste, texture, longevity. Processes that introduce weird effects and ingredients that may have a negative impact on your health.
