A bolt extractor (special sockets, with a curved sharp edge inside, that you hammer on to damaged bolts/nuts, and that grip tighter as you turn them) might work.
Get a 12point socket and hammer into it and turn it. It works for 80% and 12point socket are easy to find in almost any auto store.
For the last 20%, get a set of fancy Bolt Extractor Tool (https://www.amazon.com/gp/product/B07X7FYZB7/), just beware this can grip the bolt hardly and even break the bolt into two piece, so turn it gently once you have grip.
