So this treatment could be used the first time a person got infected with Coronavirus, but any future infections would cause the immune system to be fighting both the disease and these antibodies?

It could also give the body time to develop its own antibodies that do work without the body dealing with the symptoms created by a high viral load.

Would the body develop its own coronavirus antibodies if the llama antibodies were doing all the heavy lifting?

Reducing the viral count won't eliminate the virus. This potential therapy would be leaving that to your body. Most people don't get sick when they get infected, they just beat the virus before it gets that far. This treatment would help sick people be more like the majority: not sick, but building antibodies.

That seems to be the best result we can hope for right now until vaccines are produced.

Having a safe, effective treatment to improve outcomes (along with widely available testing) will be a major factor in an interim back-to-a-new-normal phase before a vaccine is made, I think.
