Every 100 kcal of oat flour brings 3.6 g of protein. On that measure it ranks 39th of the 111 grains in this database and 563rd of all 796 foods on the site. Measured by weight instead, its 14.7 g per 100 g ranks 5th in its group.
Around 15% of the calories in oat flour come from protein, so it is more of an energy food than a protein food. It contributes to a day's protein total, but the bulk of what it delivers is energy rather than amino acids - treat it as a contributor alongside a denser source, not as the protein in a meal.
Weight for weight, oat flour has 1.6 g of protein for each gram of fat (14.7 g against 9.12 g per 100 g).
Set against hamburger bun, another grain entry in the database, a serving carries about 0.5 g less protein (hamburger bun has 4.3 g per 1 bun).
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 quoted here is measured by volume at 26 g, and it covers about 8% of the 50 g FDA Daily Value for protein.
