The LBZ only ever had the A40 as far as I know, the A50 came out for late LMM or early LML, and then the T14 came out, before being replaced with the T87 in the 2015.5 LML.
Now if that T14 came with the LBZ and has the proper calibration to work with the E35A, then just roll with it.
Edit: it does look like there is a LBZ calibration for that 24256864 hardware, so if it has the right calibration in it. (Or if it doesn't and you can program it), I'd just roll with it.
