@California I, too mow before rototilling.
I love blackberries, but they are a really invasive weed.
In the FWIW category, I largely eliminated our previously perennial poison hemlock by waiting for a drizzly wet day in winter and then used a million BTU propane torch to steam the plants to death. I have no idea if it would work on blackberries, but it is essential that the plants are green and wet, otherwise you just burn them, which doesn't seem to get the roots. I've used dark colored tarps with a scattering of old aluminum soda cans to create a "sterilizer". Get the soil damp first, and then spread the cans and tarp, weighing down the edges. It gets mighty warm underneath.
All the best,
Peter
