Lajasvenator would win, even if its not as large, its jaws may seem better equipped for combat compared to Nanshiungosaurus.

I would probably as well - that neck is quite vulnerable, and quite a few claw swipes would be needed for lethal damage. The best chance for the therizinosaur is to keep its neck out of reach as much as possible.
I think 65/35 for the carnosaur here.
