I don't think that all the Titans are all intelligent, Zeke easily sacrificed and destroyed a lot of them when he barraged the corps with rocks. Those ones appear to be pretty mindless. Besides, as far as we know Titans are only intelligent when they are a person with shifting abilities. Levi would have cut a lot of people out of their necks when he was killing Titans the past few chapters but they're all been normal.
