I'm not sure a beginner would know what order to place them in nor would they recognize the potential injury risk associated with stacking some of these exercises.

Beginners should be focusing on form and simple compound lifts. Throwing them into things like heavy accessory lifts with no regard for exercise choice or format is a quick way to get hurt. Again, I want to applaud OP for doing this. The fitness industry is in a terrible place and tools like this have a great place. I just think it needs a ton of work to make it useful. Maybe if I find some time, I'll try and contribute but in it's current state I would never recommend something like this to anyone.

What are the odds someone is going to get hurt?

Pretty high if you don't know what you're doing with a weight that you're not strong enough to handle.

Pretty high.

Even without weights, you can permanently injure yourself with bad form. Bringing weights into the picture makes it much easier.
