So far I haven’t seen anything of the kind in the media, or even from bipartisan organisations calling for America not to provide them - for example, while Amnesty International is against the US supplying cluster munitions, they certainly don’t say it would violate international law or be a war crime.

this took but a handful of seconds to find: Amnesty International explicitly says with respect to why they oppose cluster munitions that "Customary international humanitarian law prohibits the use of inherently indiscriminate weapons; launching indiscriminate attacks that kill or injure civilians constitutes a war crime.". they consider cluster munitions to be indiscriminate. the position of Human Rights Watch is likewise that "the use of cluster munitions in areas with civilians makes an attack indiscriminate in violation of international humanitarian law, and possibly a war crime.". HRW and the UN have in fact previously documented at least one Ukrainian cluster munition attack from 2022 that killed a substantial number of civilians.
