Is there another way to determine the hybridization of an atom without drawing the molecule's lewis structure or is that the only way to determine hybridization?

In some cases, you can look at the number of electrons an atom has and where those electrons are located to determine how many regions of electron density there can be.

Basically, you can only look at the bonding regions and non-bonding regions. More specifically, one lone pair are considered as one non-bonding region, two lone pairs are considered as two non-bonding regions, etc. On the other hand, one bond, two bonds, or three bonds between the central atom and another atom is considered as one bonding region. The total number of bonding and non-bonding regions can determine the hybridization. E.g. total=2, sp; total=3, sp2; total=4, sp3; total=5, sp3d, total=6, sp3d2.

Note: exceptions still exist. But I believe this method can resolve most questions we meet.

Hope this helps!
