The TA website
says that the Pro 5 Vis uses a 111mm axle for track and 116mm for double.
The standard road bike chainline is 43.5 mm, and MTB chainline is 47.5mm (or 50mm for oversize tubes that force the front mech outwards).
The double chainline will be for a road chainline, and TA cyclotourist used as a single puts the chainring in the outer chainring position, so you'll want to subtract about 3.5mm from the 116mm (typical chainring spacing is about 7mm) to give a 112.5 mm axle.
To move the chainline out by 10mm, you'll need a BB axle that's 10mm longer on the drive side, or 20mm longer overall, giving a 132.5mm axle.
The TA Axix Light BB is available in 131mm (since I have the TA site open), which is close enough.
Chainline isn't all that critical.
A Rohloff isn't like a fixed wheel where a chain derailment is a serious problem, and almost all available chains these days are bushingless, and flexible enough sideways to easily cope with a misalignment of 10mm, as most of them have to be to cope with derailleur systems.
