I don’t think it was. The ringing of the bells signified a compromise and at this point she was sick of compromising. She already lost 2 dragons and her right hand chick. Plus everybody around her shyt talking her, questioning her authority AND the man she loves turns out to be her relative and the rightful heir to the throne. Those bells ringing were like the car horns beeping for a Michael Douglas in Falling Down. At a certain point enough is enough and just like her daddy once said, “burn them all”.
Also wanted to add another part to this. Seeing her burn of Kings Landing and the green wildfire exploding in the castle was very reminiscent of the mad king. In a sense she fulfilled his wishes. Lot of dualities happening at that moment.
