Yes, there are likely to be such fanfics out there. The idea of combining Naruto and Venom is quite an interesting crossover concept. Fanfic writers often come up with unique combinations like this to explore new storylines and character interactions.
One idea could be that Venom somehow ends up in the Naruto universe. Maybe a strange rift in dimensions brings Venom to Konoha. He could initially be seen as a threat, but Naruto, with his ability to see the good in people (or in this case, symbiotes), tries to befriend Venom. This could lead to some really interesting battles and storylines, like Venom helping Naruto against powerful enemies using his unique powers.
Perhaps the plot could start with Orochimaru experimenting with some strange new chakra that is actually the Venom symbiote. Naruto gets infected during a battle with Orochimaru's minions. With the Venom symbiote, Naruto has enhanced strength, speed, and a new form of stealth. But the symbiote also has a mind of its own and tries to make Naruto more aggressive. Naruto has to fight against this internal struggle while also facing external threats from enemies who want to use the symbiote for their own evil purposes.
In a Naruto and Venom crossover fanfic, the power balance would be crucial. Venom has superhuman strength, speed, and the ability to shapeshift. Naruto has his own set of powerful jutsu. You could have them team up against a common enemy, like an evil ninja who has also harnessed some dark symbiotic power. They would have to learn to work together, with Naruto teaching Venom about the ways of the ninja, and Venom showing Naruto some new combat techniques based on his powers.

The unique concept. Combining the Naruto world with a venom - like bloodline adds a whole new dimension to the story. It allows for different kinds of powers and abilities that we don't usually see in the regular Naruto canon.
At first, Venom might be angry at Naruto for neglecting it. But as the story progresses, Naruto could realize his mistake. Maybe he sees Venom helping the villagers in some way, like protecting them from a minor threat. This could make Naruto approach Venom and try to make amends. They could then start to train together, with Naruto teaching Venom about chakra and Venom teaching Naruto about its unique abilities.
