Oh, interesting. The code in cryptsetup to select whether to prompt via plymouth is here in /lib/cryptsetup/cryptdisks.functions:

                if [ -x /bin/plymouth ] && plymouth --ping; then
                        KEYSCRIPT="plymouth ask-for-password --prompt"
                        keyscriptarg=$(echo -e "$keyscriptarg")
                else
                        KEYSCRIPT="/lib/udev/watershed /lib/cryptsetup/askpass"
                fi

Is /dev/sda2 a luks volume, or a non-luks volume? (There are separate code paths for each) Could you try adding some debug statements to this code, to find out what's preventing cryptsetup from talking to plymouth?
