What does the vent tube do? Would it cause sand to pass through the filter into the pool?

The vent tube will help purge the air in the filter & keep it at the top of the filter. It can raise the tank pressure if it is clogged but is not generally the reason for sand back into the pool. That is usually the result of an issue with the laterals being cracked or broken. Would have a few questions, how much sand is being returned, is the vent tube screen still intact?
