There was no AOA indicator on the AF A330. I'm not sure whether it is an option. The BEA's latest report recommends that the reg. authorities study the case for making it mandatory.
On one hand it would be hard to be against it, given that during the final four minutes none of the three pilots recognised they were stalled, not even talking about it as a possibility.
On the other hand, for most of the way down it was AOA that was setting off the stall warning. Presumably they didn't think that was reliable.
