This sounds an AWFUL LOT like the killik hive mind/dark nest in star wars. Alot like it. and guess what, it did not affect the force. Jedi could still use the force against it, and could even use the force to counter it.
Tyranids actually inspired most of the other hive minds in fiction, so that there are paralels doesn't surprise me. That said, there are key differences. The Killiks don't sound like their hive mind actively messed with anyone's connection to the force. The hive mind does. The scale on which it's able to do so is pretty incredible.
I lol'd.Considering that the hive mind is the only thing the chaos gods fear, I'd say it's highly likely.
