Can you report someone for not building items?

While the Maokai in my last gameobviously trolled (he didnt fight and just stood in the backline walking around), I'm not sure that the riot system will catch that as trolling, as it wasn't explicit intentional feeding, just that he wasn't trying. However, he also only built oracles extract throughout the game, he had 6 of them in his inventory at all times. Will the report system recognize that as trolling? cause I mean, unless you recently had a major head trauma and qualify as a severely mentally impaired, then no one would build only oracles extract in a game.
