I would take them right down to the ground and put in a proper fence with proper posts. Leylandii roots are shallow and rot quite quickly once the tree is dead, which is what will happen if you remove the leaves, so your fence will not last long as the tree trunks will become unstable when the roots rot.
When you've chopped them down the soil will need lots of organic material, manure/compost and the like to improve the structure as Leylandii turn the soil beneath them to little more than dust.
Then you'll be able to grow your veggies
