Is there any way to grab it with a pliers…with the intention of destroying it to get it out? You don’t have many choices at this point.
Sounds like someone didn’t use grease on the fitting which is preventing it from coming out.
Kohler is notorious for machining their components razor close. This in turn makes it very difficult if something is crustated or calcified into place.
You might want to take some WD40 or other product to see if that might free up the cap.
