Harris is repeatedly saying that and advocating for it, including when she met with Bibi, so what's your evidence to not believe it?

“it is time for this war to end and end in a way where Israel is secure, all the hostages are released, the suffering of Palestinians in Gaza ends, and the Palestinian people can exercise their right to freedom, dignity and self-determination.”
The vice president said there has been “hopeful movement” in the talks and that she pushed the prime minister to bring the conflict to a close.
“As I just told Prime Minister Netanyahu, it is time to get this deal done,” she said. “So to everyone who has been calling for a ceasefire, and to everyone who yearns for peace, I see you and I hear you.”
I agree that as long as Bibi is in charge we have no actual leverage to get things done because he doesn't give two shits what anyone in the US says or does, but that's not the same thing as saying Harris is "pro genocide", she's not.
