is it safe to assume that any coin listed on stakingrewards with a transaction fees slider is not generating rewards from nowhere?

No, i dont think it is safe to say that.

You would need to check how those coins were firstly originated. How well decentralized really is the network
For example, do they have a master node like iota?

A master node may seems not a big deal to you, but read what the coordinator did to iota.
