This is an interesting topic. Although I don't have much knowledge in this area, randomly arranged atoms forming Boltzmann Brains and keep observing random bits handed out by universe doesn't seem all that likely to me. My main reasoning is due to how we tend to classify the knowledge coming from the observed universe, and how logically stable it is. Imagine this, you are Boltzmann Brain and track a randomly arranged consciousnesses. You sleep, go to work, eat, and sleep again as a human being. Main problem is that this kind of existence is very stable for a Boltzman Brain, as in when you wake up you see yourself in the same universe (or at least a very similar one). Now you have to ask why you are classifying these randomly arranged bits handed out by universe as a human life, but not as an alien one. Or why not you are imagining you are something supernatural like a god? Just shift the bits handed out by universe to you and next time you wake up, you will be a completely different being. It seems to me that this should be possible if you were a Boltzmann Brain and existence would be extremely chaotic. It seems to me that there is more to existence and consciousness than just reading and classifying random bits handed out to you by universe. It seems to me that logical stability is extremely important for our kind of existence and I don't see how Boltzmann Brain theory would possibly keep the universe logically stable.
