There are claims that Russian hackers tried altering the US presidential election data، Most of these claims, as far as I know, that has no verifiable evidence.
If this happened, who (person or organisation) would be legally responsible?

As a matter of law, the hacker (Russia) is legally responsible.
None of the reported hacks were actual hacks against the election process, but if they were, such an act is an act of war, as would be any other state sponsored act to interfere with the lawful succession of government. As for the infodumps from the Democratic National Convention, that's still Russia, but civil violations by a nation state are hard to pursue.
What you actually do about it is another story.
