Pancreatitis can be deadly. I hope Ollie is in the hospital on 24 hour IV fluids.
Food is not really the only cause for pancreatitis but keeping them on low fat diets is important if they are prone to it. I am sure your vet will advise you on that when Ollie
is better.
Here is a great informational link about pancreatitis:
