Well, when you consider what it actually is (statistics and weights), it makes total sense that it can inform a decision. The decision is yours though, a machine cannot be held responsible.
LLMs are a stochastic (as opposed to a deterministic) system, which can make them better at tasks that by nature are difficult to express formally, but still require a degree of certainty ("how can I make this CV better").
I believe it's slightly more nuanced than a dice roll.
