You are extrapolating very tight Israeli state control of the Israeli arms industry (very true) to very tight US state control of the Israeli arms industry, which is not actually how the relationship works.
The US has influence over Israeli sales of Israeli-made arms, but this is costly to exert and only used sparingly. Historically, it's restricted to preventing Israeli arms sales to direct US rivals like China or Russia. When Israel sells guns to dictatorships in Africa or Southeast Asia that the US doesn't like, the Americans are perfectly willing to agree to disagree.
EULAs and other civilian contractual arrangements are important here because these weapons were used against US civilians and US civilian property. When Soltam howitzers kill villagers in Myanmar, the US executive branch doesn't give a damn; but as soon as a US corporation (Apple) has to pay for warranty returns the courts wake up and pay attention.
