re: Dry laid pavers and brick

You could do a pattern of bricks/ concrete with the concrete near the tree roots.

You also might need concrete borders to lock in the brick at the edges.

Another option is to trenchdown at the edge of the driveway with the live oak and cut the roots, but then you would also need to dig out all the old roots and put an edge footing to prevent the roots from growing back.

Driveway pavers are expensive, cost would be close to concrete or more if you need to do the concrete underneath and pavers.

There are some paver manufacturers in La on the northshore or hammond, you can try calling them.
