Can tomato sauce with cooked pork in it be eaten after sitting out in pot and a/c overnight?
It is not possible that your A/C is set to 75°C. That's significantly hotter than the hottest outdoor temperature ever recorded on earth (54C or 129F). Yes, food held at 75 degrees centigrade is out of the danger zone. If, however, the A/C is really set to 75 degrees Fahrenheit (which is a normal room temperature), the food will not be safe, unless it is extremely acidic (compare ketchup). While salt can be a preservative (compare kimchi and salty pickles), excess water inhibits that effect.
