You know orochimaru's hunger for knowledge and discovering new things. If he had seen Nagato's eyes, he would surely be interested in finding more about them and hence try to take them from him and as we can see in the episode, orochimaru is right in front of Nagato to kill him so there's no chance that Zetsus could have saved him in that situation if jiraiya hadn't been there.

Also, you said that any Rinnegan bearer would get a visit from obito but if orochimaru had got the Rinnegan that time, Obito wouldn't have been able to do anything since he was just a kid at the time when jiraiya was young. And once orochimaru could tap the full power of the Rinnegan, even adult obito couldn't have stopped him.
