If she took a firm stance on stopping the killing in Gaza the electoral college could very easily hand their votes to trump.

Why couldn't they do a better job pushing Palestine as a civil rights issue and raising awareness among their voter base like they've successfully done with LGBTQ and women's rights? Or at the very least pretend to support Israel to appear more centrist while stopping the genocide instead of pretending to support Palestinians then handing Israel tons of weapons? Plus it seems like many voters are more concerned about our own economy than what's happening on the other side of the world, so regarding combining pro-Palestine with their current economic policies I don't see how that would be a big issue in attracting undecided voters. The only real obstacle I can think of here is donors and the media beholding the party to their interests, which is a much bigger problem than just the electoral college.

Edit: Wait I think I misread your post, I assumed you were talking about swing states controlling the outcome not the electors themselves.
