There could be a 'naruto kills kami fanfiction'. A plot might involve Kami being influenced by an evil force. Naruto, who has always fought for good, would see Kami as a danger to the world he loves. He might use his powerful jutsu, like the Rasengan or Sage Mode powers, to take on Kami. It could also be that Kami's actions go against Naruto's ninja way, leading to a conflict that ends with Naruto having to kill Kami.
Yes, there might be such fanfictions. One possible plotline could be that Kami has been corrupted in some way and Naruto, in his sense of justice, has to take extreme measures. Maybe Kami starts to harm the village or its people, and Naruto, as the protector, has no other choice but to fight and end Kami's existence. Another could be that Naruto is tricked into believing Kami is a threat when in fact it's a misunderstanding created by an enemy.
One possible plotline could be that Kami, being a celestial being, is drawn to Naruto's unique spirit and determination. She might start observing him from afar and gradually fall in love as she witnesses his growth. Then she could find a way to interact with him, perhaps by taking on a human form.
One possible plotline could be a case of extreme misinformation. Maybe Naruto is tricked into believing that Raikage is about to launch a devastating attack on Konoha. So, in a moment of panic and believing he is protecting his village, he kills Raikage. Another could be a dark influence. For example, if Naruto is somehow possessed by a malevolent force that drives him to kill Raikage against his will.
A possible plotline could be that Naruto is chosen by Kami for some greater purpose related to the balance of the world. As a result, they get married. Their union then brings about a new era of peace and prosperity as Naruto uses Kami's power to end all wars.

She decides to marry him, but they first have to convince the shinobi world that their union is for the good of all.
One possible plotline could be centered around the concept of Kami (gods) and Yami (darkness) in the Naruto universe interacting with Shinigami (death gods). Maybe a powerful Kami from a different realm arrives in the Naruto world and brings with it the essence of Yami. This disrupts the balance, and the Shinigami have to get involved. The characters from Naruto, like Naruto himself, could be caught in the middle of this struggle between light and dark forces related to the Kami and Yami, with the Shinigami either helping or hindering them depending on the situation.
One possible plotline could be that Naruto is somehow mind - controlled. Maybe an enemy uses a powerful genjutsu on him, making him see the Konoha 12 as threats to the village instead of comrades. This would lead to a tragic situation where Naruto, in his altered state of mind, attacks them.
Well, if there is a 'naruto kills kakashi fanfiction', it would be a very different take on the Naruto universe. It could be set in a world where Naruto has been corrupted by an evil force.

There could be a 'naruto kills jiraiya fanfiction'. It could be based on a time - travel scenario. For example, if Naruto from the future travels back in time and somehow his actions cause a chain of events that lead to Jiraiya's death. Or perhaps there's a dark, alternate universe where Naruto's values are twisted and he sees Jiraiya as an obstacle to his new, malevolent goals and thus kills him.

There might be a very dark and twisted fanfiction like that. It could be that Naruto is tricked into believing that Minato and Kushina are some kind of threat to the village or to his friends.

One possible plotline could be that Naruto is under some sort of dark magic or mind control. Maybe an enemy has found a way to manipulate his actions and make him turn on his friends.
