Am I able to see the kobolds from where I'm at? Also I'm guessing it'll be an action if I want to try and not be restrained anymore?

You are able to see two in three-quarters cover, almost below the ledge again. And yes, you would have to take an action to try and escape.

Is it possible to break that effect without it being considered a challenge to the other restraint, [@Hekazu]?

I am afraid both of the effects causing the condition need to be escaped from as an action. By you or a nearby ally.
