Trees are great in the 10-20 year range.

It's all about the right tree for the right location - and how they are grown. A tree that grows in a forest canopy will grow very tall and straight, with few branches on the trunk until it reaches the sunlight at the top of the forest canopy. This is because it has to compete with close, neighbouring trees for light. When you see those lovely tall mature trees on people's lawns, it is because there was once a forest there and the developer left that tree standing when the house was built.
When a tree grows in the open without competing with other trees for light, it will generally take advantage of the profuse sunlight and it will grow much shorter overall, but will generally have a significantly wider canopy. Live oaks have a wide, sprawling form to begin with and they'll bring a wide root system with that. Since they are long-lived and robust trees, removing them fully brings that challenge with it. They're inherently designed to be tough survivors, so they aren't going to leave your lawn without a fight!
Personally, I love forest-grown trees in the 100-200 yr range. One can try to mimic this growth with new trees by choosing certain hardwoods and planting them in a cluster instead of alone in the open. The trees will then be able to support each other as buffers during storms and wind, and they will compete with each other for sunlight, which will mean they will grow tall
quickly - each racing upwards for more canopy space and light.
If you have already removed most of the root ball and the larger buttressing roots, the radial roots will eventually die and rot. If you are diligent trimming the suckers, the resources in the buried roots will eventually dry up and the sucker growth will diminish. I would try and sever as many large roots as possible and just keep trimming the suckers. You should see them die off over time.
Then again, I don't have actual experience with live oaks...there is something kinda mystical about them with those long, gnarled limbs and that moss and all...perhaps they have other *help*....
Good luck!
