Hi, Smooth Operator.
Welcome to EvC!
I hope you don't mind my butting in.

Randomness has absolutely nothing to do with causation. The concept you are thinking of is described by the term "spontaneous." Mutations are not spontaneous: they are random.
Randomness only deals with incidence and uncertainty, not causation. It implies that there are multiple options, no one of which is guaranteed to come to fruition, but any one of which could potentially happen.
This is a perfect description for bacterial mutations, with or without the inhibitor. Turning on the inhibitor increases the likelihood that a mutation will slip past the repair machinery, but it does not cause mutations to happen. The bacterium is still reliant on the usual causes of mutation to make mutations happen.
If the inhibitor is on, mutations are caused by DNA replication errors, chemical imbalances, radiation, etc.; if the inhibitor is off, mutations are caused by DNA replication errors, chemical imbalances, radiation, etc.
What you are calling "induction" is not causation, it is facilitation. This means that anything that happens under induction could happen without induction, but it would just happen more slowly.
