What are your thoughts on IIT Madras offering a bachelor's degree/diploma online?

It is a full-time degree or diploma and so it will have more value than online. But if we compare IIT Madras’ online degree or diploma with any other college’s then it is better.

The duration of the course is 3 years. The mode of training is online, the lectures are mostly recorded and partly live sessions.

Whether the course will be good or not that depends on what subject you are planning to pursue. If you opt for a subject related to technology, then it is not a good option. This is because technology cannot be learned through books or audiovisual. It requires you to be present in the field to gain experience and knowledge.
