From what I can gather from reading up on this, Torque Steer is a combination of factors. In the old days, most FWD vehicles had un-equal drive shafts which caused Torque Steer due to the longer shaft having a different "twist" characteristic as well as being on a different angle to the wheel. Now most implement a "equal length" solution by using an intermediate shaft, then the final drive shaft, which has an equal length to the other (closer)shaft.
I did find this link to an article describing how steering feedback settings also have an effect on Torque Steer:

Notice the authors opinion of: "For this reason MacPherson suspension strut may not be very suitable for FWD cars with very powerful engines." Interesting!!
IMHO: It sounds like a true "Limited Slip" system is the only real solution.
