Morphology
The verb 'tell' already conveys reporting, so a B1 learner who knows the constituents may suspect this MWE relates to reporting someone. However, the particle 'on' does not transparently encode the sense 'to inform an authority causing trouble'—the specific accusatory/reporting nuance is a phrasal-verb collocation that typically requires prior exposure.
Etymology
Tell on comes from the idea of the verb tell meaning 'to show' and the word on, so something can 'show on' a person — for example, years of hard work showing on your face or body and making you look tired or weak. That's why it means 'to have a noticeable or damaging effect'.
