Drains should always have a P-trap within so many inches of the drain opening. That prevents sewer gas from escaping from the drain. This is what should be there if it’s a sink drain.

The issue with a vent 90/elbow in a sewer line is that they slow the water flow and can easily become obstructed. Normal elbows are curved to help prevent the water flow from slowing down.
