I don't know the UW criteria Citi uses for BIZ versus Personal, but it seems that all your BIZ cards are Amex. So none are likely reporting to the CB that Citi will use. So unless you have other scoring factors not listed, it will be based soley on your Personal score. Which looks okay.
Also not sure what Citi feels is "credit seeking" behavior.
My Personal AAdvantage was apped on 4/18, my AAdvantage BIZ app was 10/19.
