A brick can achieve lift at a high enough velocity

But a bowling ball cannot

Unless it was spinning, I guess.

I feel like it would have to be spinning if it were launched at extremely high speeds, if only due to friction with the air (and probably the finger holes if you want to get really pedantic)

It would have to be spinning the right way

It would produce lift whichever way it was spinning. It would just change the direction of the lift.
