Correction: AI is not deterministic, the only realistic low-error solution is not a more complex use of non-deterministic AI, but deterministic transpilation.
The problem is that this results in COBOL-in-Java which runs correctly but it is a nightmare to maintain.
AI (LLMs) is typically not run deterministically for performance reasons, but can be turned deterministic if you want it to be. The output will still be probabilistic, however, so you will be no further ahead. Determinism isn't helpful.
