I’m very confused by the problem in a packet my teacher gave me, which states Al(s) + N₂(g)  2ALN(s)

I reviewed this question with my teacher and he said it was correct, however wouldn’t that make the equation imbalanced, since there isn’t 2 Aluminum atoms on the left side of the equation?

You are right - reaction as written is not balanced.
