but there’s the other side to the coin, which is, how do you then “hold nature accountable” for its “actions?” By that I mean natural disasters.
No, this is not part of legal personhood. Essentially every legal system has a version of juridical personhood (i.e. a personal entity only in legal proceedings), and they do not allow for this kind of ad absurdam approach to the legal liabilities of an entity. They spell out exactly what kind of liabilities an entity is subject to, and natural disasters have never been put forth as part of non-human natural entities.
