No, money has nothing to do with it. The US military aid package to Israel is only around 2-3% of Israel's annual state budget. That's a relatively small amount, and far less significant than people tend to make it out to be.
The US provides this aid because it serves American interests. A large portion of the money is actually spent in the US, benefiting the American defense industry, not just financially but also through technological development and shared innovation.
What Israel truly gains from the relationship with the US is diplomatic cover, mainly the UN Security Council veto. Israel is by far the most condemned country at the UN in terms of resolutions passed against it, whether that's justified or not is a separate debate.
