Long story short, I mixed up the torque values for the bottom bracket cups and pinch bolts on a Shimano Hollowtech II BB. I ended up rounding the head on the pinch bolts, any recommendations on how to remove the bolts. Would something like this work, https://www.harborfreight.com/12-piec...set-40349.html. TIA

I just take a drill same size or one smaller as the bolt threads drill down approximately the depth of the head only the head will pop off or be very loose use a pick to remove the head. Tension will be removed and the remainder of the bolt will turn easily and remove it.
In your case the arm will slide off remove the bolt inside threads.
