Is it safe to cook pork chops that thawed on counter overnight?
No. It has been out in room temperature for far too long to be safe to eat. Pork chops will be completely defrosted after 2-3 hours, which means they have been in the 'danger zone' for 6-8 hours. If you are defrosting over night, I would recommend putting it in a bowl of water in the fridge.
