Hi Jesse,
I've had a quick search and whilst there are a few ssd1306 node.js modules available, it doesn't appear that anyone has wrapped it up as a node-red node. That's going to make this more challenging for you.
I would start by looking at the ssd1306 node module you want to use, hopefully it'll provide some examples for driving it directly with a simple node.js application. If you can get that far, we can then explore how to move that into a node-red environment so you can wire it up to whatever events you to trigger it.
