Tim,,I think you will be relieved. ,
i removed a ceanothus for someone a few years ago....it was crashing into the gutters etc when windy and was pretty big......at leasf as big as yours.
no, get it all out. Cut it back so you have a 6' or so trunk to lever with. with all ceanthus I found the roots quite brittle and relatively easy to remove.
secateurs, loppers, a saw, spade, fork and ...I always use a crowbar.
When you have just the clean 6' stem start digging a trench around if......cut roots as you see them....and push and pull to further break roots.
Some swearing,,cursing and sweating but you will get it out.
Never leave stumps.....just creates problems for future planting
