I strongly suspect that there is no reason to add TaintedDiv here -- this not a normal test run, but an intentionally wrong invocation that passes an invalid config file name and verifies the error output with FileCheck.

In fact, I also suspect that you could remove the ExprInspection line below this without changing the meaning of this test. (You should perhaps do it for the sake of clarity.)
