[Lord of the Rings films] Could Saruman have shot fireballs down at all the Ents that were invading Isengard?

Yes, he could have. He didn't follow the rules the Istari were supposed to follow, particularly on not using the full might of his powers unless the situation absolutely demanded it (e.g. Gandalf battling Durin's Bane). Perhaps the fireball was an extremely powerful spell and he couldn't spam it.

Edit: Typo.
