Tufo's can't be repaired in a traditional sense, because as you say, the tube and tire is a "unibody"
That said, the concept is that the "unibody" makes them more durable and "designed" to work with sealant to seal small leaks.
In both types of tire, a large slice largely makes the tire toast.
For smaller punctures, sealant can be added after or before, as a preventative measure.
Sealant in a traditional tubular has varied results, and the sealant will be squirting from the tube into the casing before it seals.
I had some luck a month or so ago on one of my Vittoria Pave with sealant, held enough to get home, but was not a permanent fix - once I pumped it back up to 80 it held until half way through the next ride, then flatted again.
With the Tufo, the sealant makes more of a permanent fix (except for large cuts).
