Well, "Front End AXI Input block" refers to inputs read from memory, not received on the streaming interface (which is specified to be 16-bit LE).
It's possible you could make this work using a custom DT (i.e. not RAW8, which would get padded to 16 bits, then Decompress won't be able to deal with it) and configure different widths in CSIDMA and ISP-FE, to deal with the 16-bit/8-bit ambiguity that arises...
But it's not necessary to hack it like that! The Decompand block should be able to decode mode 2 perfectly. (Having said that, it's not been heavily tested, but I think I'd still recommend trying Decompand over Decompress.)
