I generally use nominal reinforcing just to hold the concrete together. The HSS column is really doing all the work and the concrete is only adding bearing surface for the lateral soil bearing pressure. But -- you probably can't find anything in the code that says you don't need any reinforcing. On small things like this I always let the plan checker win :<)
I'm not sure what you mean by the flatwork providing "restraint against rotation" unless you mean providing horizontal resistance at the ground surface. In that case you have to figure the amount of concrete, its weight and the coefficient of friction to resist the horizontal load (couple). If there is not enough to resist the force through bearing and shear of the concrete then I add horizontal reinforcing steel around or welded to the column to drag it where I want it.
