It’s equally valued, if someone says a snake is not poisonous they are usually meaning that it’s not venomous, as there’s very few contexts where people are worried about the risks of eating a snake, and very few are poisonous.
So yes conversationally the rat is right as he knows the concept is mis implied.
However, it’s also worth pointing out that, the story doesn’t tell us whether the snake is venomous at all. He’s drawn with fangs so, maybe, but it’s entirely a moot point because snakes don’t need venom to kill a mouse.
The snake is right though, it’s not poisonous. It is venomous, do there’s no good reason for the rat to ‘correct’ it.
Be quiet or the snake eats you
I’m not afraid of the snake, it’s not poisonous
Your lack of fear won’t stop stop the snake from eating you anyway

So we shouldn’t feed the troll…hmm…
What about feeding the troll with poison?
Also even if it isn’t venomous, it still eats critters.
