I had a toy when I was a kid that took 6 AA batteries. Now I know that means it wanted around a 9V input. But why did it take 6AAs instead of one 9V? The 9V would’ve been smaller and lighter, wouldn’t that have let them make a smaller battery compartment and save on manufacturing costs?

Voltage is just one requirement. Amperage requirement is another. The larger cells of multiple batteries is able to provide more Amperage and will also usually last much longer. Typical requirement of kids toys.
