There a few things getting mashed up here, so let’s start by saying No, it’s silly to pay extra for BSA.
Now, creaky BB is very unlikely to be a problem with a new Litespeed Ti frame because metal machining is accurate. Creaking is caused by imprecision in the BB bore spec, and is almost exclusively an issue in carbon fiber construction, and results pressfit BB’s cannot overcome it.
Next, T47 is not a pressfit BB anyway, it’s threaded.
The benefit of T47 is that it’s oversized, and better suited to making stiffer frames and fitting various crank spindle diameters. It’s better than BSA in this regard.
Litespeed are saying, essentially, that they prefer to work to modern standards but will accommodate silliness if you pay them to do so.
