The effect is manifested either as a tugging sensation in the steering wheel, or a veering of the vehicle from the intended path. Torque steer is directly related to differences in the forces in the contact patches of the left and right drive wheels. The effect becomes more evident when high torques are applied to the drive wheels either because of a high overall reduction ratio between the engine and wheels,[1] high engine torque, or some combination of the two."

I know it says "especially front-wheel drive" cars but maybe my issue is part of the exception

You have two different tires on a LSD. There is no mystery here. The power steering is not meant to fix this and is not the issue.
