It wasn’t useful for Harris to call it a genocide, because it would have hurt her chances of getting elected. Even Bernie refers to it as a war, probably so he doesn’t get censored by the Senate.
Harris called for a ceasefire multiple times. Here’s a comment that said it best.

She’s taken a stance, multiple times. The left doesn’t want to hear it.

Despite your argument’s attempt to conflate the two, it was evident from examining the evidence that Harris wanted a ceasefire and would be better than Trump on this issue. To end the genocide we need a president who wants it to end before all the Palestinians are dead.
Biden wasn’t running for president. Harris was and as VP she doesn’t have the power to change the US’ relationship with anyone.
