At a first glance, it seems that something may have gone wrong in the alignment of the MCTs. As you may know, these work on the basis of marketing flight numbers.
A quick look on ExpertFlyer suggests that AA-BA is 2:00. This is a specific line that says "AA-BA II 2.00 ALL - UNITED KINGDOM".
However, AA-AA and BA-BA are 1:15, and it is not hard to get ITA to price itineraries with 90 minute connections on both combinations. (Theoretically, BA-AA is also 1:15 but I can't find any connection like that, so it may be illegal for other reasons.)
At a guess, AA wanted to impose a 2:00 MCT but only managed to file it / get it filed for AA-BA (ie the operating combination) rather than the other possible marketing combinations. That would explain why the BA call centre and ITA will still happily sell your 90 minute connection.
