The source hasn't been lost. It's just that the source was written in a combination of assembly code and COBOL, before COBOL was standardised. They can turn and recompile it any time. Doesn't mean that it's easy to modify or maintain.
There were successful efforts to translate it to Java, already underway (CADE-2). They were probably going to finish somewhere in the next two years. The efforts were for bit-for-bit identical reproductions. [0]
An AI will not help you here. Because this little piece of assembly was created for mainframes, not for computers today (AS/400s, I believe). Even the concept of paths don't operate the way systems do today - the drives were direct access, and tape-based.
There is not enough material to train a model on, to make it close to accurate.
