i use sprawls as a counter to shovels and leg grabs. against a single leg grab want to try to grab them on the grabbing arm as close to the shoulder as possible. sit heavy on the back leg. with my free hand i want to strike or lock down limbs. once i've sat down to prevent any lifting shenanigans.
the best place i've found to practice sprawls is against a shovel. against a shovel i want an upper arm grab with a contracted wrist and straight elbow to create a T. twist the hip on the same side a the grab away to give you more space to play around with. once you have your T. let your standard skill set take over.

grab prefferences + reasons
over the top hip grab either side- feels like i can sit heavier and my arm is already stretched out for saves.
underhook to leg. very strong leads to slower games
underhook to body can be used with or without grabs so you can toggle for ghost disruption.
over hook good starting point can be used with or without grabs

TLDR: sprawls are applicable in toribash. not as a finisher but as a control postion
