I suspected you'd know, but I thought it was good to clarify who Moshe Arens was for other people reading. ;)
The article you link is interesting, and it mentions a special tax that would be levied on the populace to continue funding the project. Which gives you a hint about how expensive it was! It also mentions that the US didn't like the project. But if US pressure was factor, then why was the project started in the first place? Recall that in 1987 the project was over 10 years old.
Fact is that Israel does a lot of things that the US does not like, like building settlements, but it has never used the military aid as a means to put pressure on Israel. So sure, the US could theoretically exert influence by threatening to stop the aid, but it hasn't done so and probably won't. It would be too much like slaughtering a holy cow for them.
The Lavi story isn't unique. Half a dozen countries have tried to build fighter planes but then cancelled the programs because they were too expensive. I believe the only countries currently producing modern fighter jets are USA, Russia, France, EU, China and Sweden. And I can tell you that the Swedish fighter jet program has been incredibly close to being cancelled numerous times over the last decades.
