Can I get some guidance on what function I should use to insert a .byte/.word in SelectionDAG so it’s printed out in assembly?

As far as I know, up to the CodeGen phase, LLVM works on a
target-agnostic representation of the original code; low
level concepts, such as ASM directives, are not handled; thus, it is not
possible to add them in the SelectionDAG or
in the subsequent machine specific representation.

As pointed out by Tim, you could print them during the code emission
phase [1].
