There is no reason why an AI should never castle without book. I am pretty sure that the included Fairy-Max and KingSlayer engines would castle very quickly. I don't know about ChessV's intrinsic AI, but if it never castles it means the evaluation can easily be improved. In KingSlayer the castling is driven by a bonus for having a King near a corner behind a Pawn shield.
I guess that conventional chess AIs (i.e. not the alpha-zero type neural networks) are always mostly tactical.
