Just having the Spell Hand Feat isn't enough for Arcane Trickster...you need to be able to cast a spell of 3rd level or higher too, which is the much harder aspect to fulfill. As a DM, I'd be willing to waive this requirement with being able to use Lesser Invocations, but RAW, Warlocks have a much harder time of it than burning a Feat to get in.
