Simply look out for libraries imagined by ML and make them real, with actual malicious code. No wait, don't do that
No?
An anthropomorphic model of the software, wherein you can articulate things like "the software is making up packages", or "the software mistakenly thinks these packages ought to exist", is the right level of abstraction for usefully reasoning about software like this. Using that model, you can make predictions about what will happen when you run the software, and you can take actions that will lead to the outcomes you want occurring more often when you run the software.
If you try to explain what is going on without these concepts, you're left saying something like "the wrong token is being sampled because the probability of the right one is too low because of several thousand neural network weights being slightly off of where they would have to be to make the right one come out consistently". Which is true, but not useful.
The anthropomorphic approach suggests stuff like "yell at the software in all caps to only use python packages that really exist", and that sort of approach has been found to be effective in practice.
