I don't think that, at least during the Republic, lower ranked officers would take tactical decisions on their own during battle. They probably had some very small degree of flexibility as to certain aspects within the Roman battle-line system, like when to retreat a bit to keep cohesion with the nearby cohorts or maniples, but nothing extreme. They did not have the freedom to leave their position, maneuver in a different manner than was prescribed in the pre-battle orders or general commands if that is what you are asking. If you are referring to detachment tactics, that would be another issue.
The question would be what you mean by 'making decisions on their own' and 'designating responsibility'?
