Not aware of any OOTB report to produce list of such report def rules, but you may follow these solution -
Normally when you save a Report def rule with reference to a property in BLOB, PRPC adds a guardrail warning to that rule (e.g. "These properties are not optimized: .pxDebugSwitch. Displaying them may result in poor performance. Consult your system administrator about optimizing properties for reporting.").
You can download the list of guardrail warnings from that application and look for such warnings.
