Hi Prep,
You're dead on about the LSAT's "central causal assumption," that there is just one cause for each effect, and that we know what that cause was. You will see some stimuli in LR in which the author explicitly references the possibility of multiple causes, or explicitly indicates less than certainty as to the cause. As you mention, the conclusion may be that "A probably caused B." In that case, the stimulus author has left some wiggle room, but it likely is still a flawed argument, because typically the stimulus won't contain the evidence necessary to reach even a probabilistic conclusion dealing with causality.
Although the LSAT tends to deal with causality in this way, always be sure to consider the entire context of the stimulus so that you don't get caught making your own assumption, that LSAC can never sneak in a valid causal argument in a LR stimulus.
Best Wishes,
Ron
