Gosh, you’ve got a job on there, I think, if you don’t mind, Could I copy your photo as a lesson to posters thinking of planting Leylandii, this is what they grow like, I can see how wide they were by the dead ground around them, taken up half the garden and had the fence down!
Assuming that fence is yours, l would certainly start with replacing it. If not some form of disguise is required !Are you planning to leave the stumps in situ, or will they be ground out? As Josusa says, that soil is going to need a lot of compost etc. added.It looks like a very sunny site, what sort of planting would you like? Shrubs, perennials, vegetables ?It seems quite a bit lower than the lawn, maybe raised beds ?

cancell your gym memberships, you will be super fit, by the time you have tackled that area!I think you should get as much of the stumps removed as possible, then sort out that fence.
What is that hedge behind the fence? If it’s something that will grow back to cover the bare wood then that might solve all your problems, and not cost a penny
