Normally you would make a copy of your product and then create a plaster mold in sections. The number of sections woud be determined by the complexity of the form. After the plaster is set and dry, clay slip can be poured into the mold.
You need to make sure to drain the excess slip after set up. Addition pieces can be slipped in place after removed from mold.
You cannot fire extremely thick clay, it is likely to explode.

I have never heard of one. I make molds from castable materials that can be fired but the resulting mold is not smooth enough to contain a finished product. There are mold making consulting services that might be able to help you. I don't think you will be able to get away from multiple part molds if you have so many undercuts.

I think the closest your going to get is a cold cast porcelain resin, which you probably already know about.
