Also, is there any register bit or pin offering information on
"normal" vs "BSL" status?

I've never seen an app note that discusses it. However, my
understanding of BSL mode is that it is implemented as an actual
MSP430 program resident in mask-ROM on the chip. This implies that
unless the program specifically initializes unused pins, all I/O
drivers will be in the POR state, which in almost all cases is hi-Z.

You should check this on a device specific basis with your TI FAE. But
I would bet money on it.
