The rocket decelerates quickly during quite a short landing burn, so they would have had a strong effect until the last few seconds. Indeed, the loss of that force as the rocket comes to a stop would have been an important part of the crash - the rocket would have been countering the influence of the grid fins pushing the top of the rocket away from the camera, while tilting the rocket toward the camera to get it back to the platform. Then the rocket slows and that force dies away. Now the rocket has to go from working hard forcing the rocket to tilt toward us against that force, to trying to push it back upright with that force suddenly gone. You can see that it was trying, because the rocket flame is directed away from us, illuminating the far side of the rocket, leaving the near side in darkness.
Nope. Grid fins explain what we see very well.
