If someone is short, with short legs compared to torso, will this be a limiting factor in how fast they can sprint? Since generally top end speed is determined by stride rate x stride length

That needs to be balanced against start speed. In my experience, the guys with shorter legs tend to start faster, but the taller guys have better top end. That's why Bolt's a freak - he's a tall guy who can still start quite well.
Others may have actual evidence one way or the other for this, but what I've observed is that 100m guys tend to be smaller than the 200 / 400 / 800 guys, but marathon runners tend to be relatively short. I imagine that's something to do with the tradeoff between stride length and the extra weight involved in having longer legs.
As a fairly short sprinter, I find I often beat the big guys over 100m (and the Masters event of 60m), but they tend to run me down over 200m / 400m. That could just mean that my speed endurance is crap of course.
Yes, Shelly Ann Fraser Pryce has no chance of being a fast sprinter.

It's not generally, it's SPECIFICALLY determined by that.
What does that equation have to do with leg length? Neither of those two say "leg length".
Well stride length and length do correspond generally. Stride length is determined by leg length x power output

Stride length has little to do with leg length.

No it is not. Stride length is determined by body weight and takeoff strength (or power or whatever you want to call it). Leg length is irrelevant.
It is not leg length that determines stride rate, but the amount of force applied at push-off. Leg length is a factor in push-off force, but the latter is not a function of the former.

Wrong and wrong.
