Structural columns or not?

​Florida structural engineering question. This house has rotten wood columns. 6 columns and all are hollow, not structural, I think. The distance from the brick wall to the fake column lintel is 6'1, wood frame house, slab on grade with the exception of the porch. Are the columns holding the lintel or are the truss tails holding it. The thing that bothers me are the hurricane straps are at the lintel. Thats fine and dandy but the up lift is troublesome. Even when new.... a few toe nailed columns to the deck boards wouldn't hold squat. What am I missing here.

It depends. How much do you like your neighbor?

The new columns I bought (similar replacement) are rated at 3200lbs each. Thats a small chevy, right. and I have 6 columns.

The other matter is that even if the trusses were intended to cantilever, there doesn't appear to be enough bracing between the trusses at the bearing along the back wall of the porch. The trusses would need this restraint to achieve design load.
