Many a times, led ON is done in software as a digital output. Secondly, I can imagine if rent to own places turned on the camera whenever the computer was on, people would just get used to it. Make it normal and nobody doubts you. Thirdly, I would say that most of the people using rent to own services aren't interested in the inner workings of computer hardware, or even understand basic computer topics. To these people, it is a tool required by school, work, or casual use. Even if you told them that it would record you, they'd not have an idea to stop it, perhaps other than tape. And tape doesn't stop audio recording, or remote takeover software.
