They had extensive hangar facilities, yes, but still just ordinary revolving catapults. Mogami received an actual (very short) flight deck, much like Hyuuga and Ise. You can see this fairly well on this photograph:

Note the flat area seemingly empty of catapults in the back.

The CAV/BBV definition in Kancolle is used for ships that received a short, multipurpose flight deck for floatplane operations. Ise, Hyuuga and Mogami received this modification historically, and do so in the game very early to reflect it. The rest of the Mogami class, Fuso class and Tone class didn't receive it historically, but could potentially have, and their Kancolle counterparts reflect that kind of hypothetical development.

Tone and Chikuma at Kai Ni are no longer the same warship that they were at Kai - they exchanged part of their rear facilities for a short flight deck. You can easily see this in Chikuma's design:

The black front of her china dress is her newly acquired flight deck; the lines are the fixed-angle catapults.

The definition for Aviation[...] isn't at all unclear or ambiguous in Kancolle. Aviation ships have a flight deck. That's it.
