The villagers of Konoha would be divided. Some would trust Kakashi and believe there was a good reason for Naruto's death, while others would be furious. The older generation, like Tsunade if she was still around, would demand an investigation. And for Hinata, she would be the most affected. She might feel like she lost her purpose in life with Naruto gone, but then find new strength in seeking justice for him.
One possible plot could be that there is some sort of misunderstanding or dark magic at play. Maybe Kakashi is being controlled against his will. In the 'Naruhina' aspect, Hinata could be devastated by Naruto's death. She might initially suspect foul play within the village and start her own investigation, all while struggling with her grief and her unfulfilled love for Naruto.
Yes, there might be such fanfictions out there in the vast world of fan - created content. However, this goes against the general storyline of the Naruto series where they are comrades.
In a lot of Naruhina fanfiction, Naruto is indeed OP. His character has so much potential for being OP given his origin in the Naruto series. He has the Nine - Tails within him, which is an incredibly powerful source of chakra. In fanfiction, authors can take this and run with it. They can make him so strong that he can change the whole ninja world on his own. When it comes to Naruhina fanfiction, his OP nature can also be used to show how he protects Hinata, making their relationship more endearing. For instance, he might be able to take on entire armies to save her, which is a common trope in such fan - made stories.
There's a fanfic called 'Jealousy's Stirrings'. It delves deep into Naruto's jealousy when it comes to Hinata.

It also has some action scenes intertwined with the emotional drama.
Yes, there might be such fanfictions in the vast world of fan-created content. However, this is a rather dark and non - canonical concept as Kushina is Naruto's mother and is usually depicted as loving in the original series.
It's a rather unique concept. In the original Naruto series, Kakashi is a mentor figure to Naruto. The idea of Kakashi killing Naruto goes against the general bond and narrative. So in fanfiction, it's not a common theme as most fanfics tend to follow the positive relationships from the original. However, it can attract those who like exploring dark or alternative storylines.
The other villages might react with a mix of shock and suspicion. They knew Naruto was a powerful force for good in the ninja world. His death could be seen as a sign that something was amiss in Konoha. Some villages might even fear that Konoha was becoming unstable and could pose a threat. Characters like Gaara, who had a special bond with Naruto, would be deeply saddened and might try to find out the real reason behind Naruto's death.
One possible plot could be a dark turn in the story. Maybe Kakashi is under some kind of mind - control. He could be forced to fight Naruto by a powerful enemy who has taken over his mind. Naruto, being unprepared for such an attack from his mentor, gets killed. This would then lead to a series of events like Sasuke going on a rampage to find out the truth and avenge Naruto, and the whole ninja world being in shock as one of their most promising heroes is gone.
In this type of fanfiction, Naruto leaving Team 7 can be a very emotional and plot - twisting scenario. It might lead to Hinata stepping up to support Naruto in different ways.
