Yes, though a human could do better, it did at least correctly identify the verb being used, イキる (a slang term meaning "to get cocky", "to act arrogantly", etc.), which is the only grammatically possible choice there as far as I know.

i.e. the dictionary form of いきって must be いきる（五段）, いきつ, or いきう ― I don't know of any other 五段 verbs read as いきる, or any verbs read いきつ or いきう. The original MTL's choice of イク would conjugate to いって, and e.g. 生きる would conjugate to いきて, etc.
