I'm not at all certain about the roll rate of the P-38L in AH. I have not done any testing. I'm sure several others have.
However, you must remember that the hydraulic assist for the ailerons only made it easier to turn the yoke against the resistance caused by airflow at high speeds. The biggest advantage of the hydraulic assist was that it allowed a fast snap or flick roll at HIGH SPEED. The P-38 only had a fast roll rate at speeds above 250MPH, and only held an advantage in roll rate above 300 MPH. And then only the models that had hydraulic assist on the ailerons. It would still only approach, and I do mean approach, parity with fast rollers like the FW190 and the P-47.
On the other hand, the P-38 could roll equally well in either direction, and flew with neutral trim regardless of power settings.
A single engine fighter had to use trim to maintain normal flight with constant stick input, and trim had to be changed with power setting changes. They do not roll equally well in both directions due to the torque. Rolling with torque they rolled quickly, rolling against torque they rolled slowly and risked stalling. A favorite tactice of P-38 pilots was a climbing right turn. When they forced the enemy fighter to a low enough speed in the climb, if the enemy continued pursuit, he'd stall and snap roll inverted and possibly out of control. He then became easy prey.
When evading the enemy in a dive, P-38 pilots were instructed to immediately climb out to the right after the dive, because it was harder for the enemy to follow at high speed and high power settings.
The problem is that the P-38 has a 52 foot wingspan, and broad chord ailerons. They really aren't as effective as they could be if they were redesigned. Add to that the inertia brought about by the weight and width of the P-38 and you have a slow roll rate at low speed, and a high yoke effort at high speed without hydraulic assist.
