Yes the US probably is still using precision weapons because, well, unlike the Iranian government we don't want to use so-called dumb munitions and indiscriminately bomb civilians or civilian targets. And of course in general, why even fly into the airspace if you don't have to - malfunctions happen too.
Are you referring to the "precision" weapons that hit the girls' school?
And the US has been very keen to bomb civilians and civilian infrastructure, along with Israelis, since the start of the war [0]. The US-Israelis are guilty of war crimes.
The recent bombing of an unfinished bridge is another example of the US-Israeli actions, especially since they did a double-tap to kill rescuers. [1]
