A sauropod probably could not run like that but probably could move with some measure of speed when necesary. A cow does not have pillar like legs nor a large tail. This changes the dynamics.

What is risky about reaching up and grabbing a sauropod by the neck, if
you match the physical description of a tyrannosaur? If your hold is 2m
behind the head, you are 8m away from the front feet. Even that assumes
no injury to the spine of the prey item, which would result in instant
incapacitation of the prey.

It 'looks like' to me like you are characterizing prey/predator
interactions on the basis of sheer intuition, and are overly impressed
by simple size differential.

That neck is still capable of swinging around and some sort of violent motion should be expected in response. Depending on the size of the sauropod, incapacitation would not seem like a given. In fact, it might even hurt the predator.
