Not likely, the LSD is a torsen, true, but it's only a group of gears and has no parts that can slip, spring, slide or vibrate. And driving in a straight line means the torsen mechanisms (worm gears) effectively do nothing. Considering the very small number of people experiencing this, it could simply be a batch of plates were made/machined in such a way that they are a bit sensitive to particular shifting styles, and the clutch plate vibrates on heavy slipping at certain RPM and engine load. I agree a slightly delayed shift/application of gas may help, slamming through gears and dropping the clutch hard every shift certainly isn't going to be good in the long run, and vibrations sometimes feed themselves and get worse.
