Try standing directly in the path of one of the pillars, barrel roll to one side, just in the nick of time and then roll to the other side for the next one and continue this pattern.
This Griffon was easier than the previous one, I thought so at least. Avoid doing air raid, it might be better to use Ifrit and have your grenade gun at the ready. That's how I won anyway, If you knock him over, pound him with either inferno or kick 13 level 2 DT combos.
The jump stomp is easy to avoid, just switch to Alastor and run in DT, with the Grenade gun DT rapidly charges up.
