Is it harmful to a submersible pump to reduce its GPH output by using an inline ball valve? Is there a better why than what I suggested to reduce output?

Depends on the amount of reduction. Pumps benefit with from a certain amount of resistance whether it be from friction loss or restriction from a valve. A pump that is allowed to spin freely will quickly overheat, even if submerged, and fail. There is no justification for severely impeding the flow of a pump. If considerably less flow is desired, use a smaller pump. You are just wasting electricity with the larger pump.
