If you don't believe that United States law extends outside of its jurisdiction the Coast guard would like to have a word with you which enforces US maritime law around the world in international waters. Additionally US routinely enforces its law in various aspects around the world in different countries. The US also controls what laws from other countries its citizens are allowed to enforce.
Lastly Google being a US company that operates internationally, they should absolutely refuse to honor any of this as it is in direct violation of the laws of its home country.
But that order must be enforced by Google. Argentina cannot enforce it unilaterally arbitrarily without Google's help. I'm not sure you understand the mechanism of enforcement that they are requesting.
Unless the US passes extensive legislation to prevent US companies from unlawfully accessing their clients devices all over the world, Google will comply. But the US isnt likely to do that.

Do you have a specific complaint? US courts do not allow lawsuits for things that happen in international waters unless they pass an 8-part test.
But at the same time, UN law of the sea treaties say that any nation may combat piracy in international waters. On top of that is the UN Convention for the Suppression of Unlawful Acts against the Safety of Maritime Navigation [1], which adds a number of additional acts that any nation may enforce in international waters. But you should probably be glad that the US is doing the bulk of this: The United Nations is perfectly ok with a sham "trial" of any suspected wrong-doer followed by summary execution and throwing the body overboard. The US does not allow that.
