Yeah I mean I'm not that interested in debating the definition of "irony", but it just doesn't strike me as ironic at all that AI is good at doing the grunt work to expose a bug like this! If you think "wow, it's ironic that AI can be used to improve software quality" instead of "well yeah, this is exactly the kind of thing that AI is good at", then IMO you've got your priors about AI mixed up.
