There is in the sense that casualties per day were highest during the initial, random bombings of everything and everyone in Gaza. Did Israel commit a genocide then? Possibly, ICJ’s initial ruling certainly suggests they suspect this might have been the case. The question (which was what I was commenting on) then becomes, what could the US do to prevent that? They could have stopped supplying Israel with weapons, which would have made little difference as Israel don’t really rely on military donations from the US anymore. They could have ordered Israel, through the Security Council, to stop the war. There’s no guarantee Israel would have listened, they may just have gotten more aggressive if they felt isolated and abandoned with noone to answer to. Or they could use the fact they have a direct phoneline and a cordial relationship to exert diplomatic pressure, which is what they have done, or tried to.
