Not really a plot hole.

Kakashi can still bring light to the situation and the Manga is not over, so plot holes do not exist yet.

And he probably meant it like Kakashi failed his promise to Obito.

Because Kakashi was supposed to make sure Rin was safe, but he failed. So saying "You let Rin die" is a fair thing to say.
