A typical 10 olives serving of green olives contains 0.3 grams of protein (1.03 g per 100 g), which makes it only a minor source of protein. That covers roughly 1% of the 50 g reference Daily Value, so it adds toward your protein total for the day.

It is an incomplete protein on its own; pairing it with other plant foods across the day covers the full range of essential amino acids. The serving above is counted by piece at 27 g.
