You could use the LLM to help you write utility scripts for whatever disassembler you’re using e.g. python for IDA. That might work better than feeding it raw assembly.

Game RE communities also have all sorts of neat utilities for decompiling large cpp binaries. Skyrim’s community is pretty active with ghidra/ida.

Guessing you’re not lucky enough to have a PDB?

PDB?

Program database file - only relevant if the binary is Windows. But that makes decomp an order of magnitude easier. I’d be surprised if OP had one though.
