Yes, there are likely fanfictions out there with this concept. The 'Harry Potter' fandom is vast and creative, and many fans like to explore unique and alternative storylines. Some might imagine Harry having a special connection to the idea of 'Lord Death' in a fan - created narrative.
A common theme is identity. Harry would constantly be grappling with who he really is. Is he still the same Harry Potter we know, or does his new heritage as the son of Lord Death change everything? There could also be a theme of secrecy. He might have to keep this new part of his identity a secret for fear of how others would react. And then there's the theme of redemption. Maybe his connection to Lord Death gives him the power to redeem those who have been touched by the dark side, like some of the Death Eaters who might not be fully lost.
His relationship with Dumbledore would be very different. Dumbledore might be more cautious around him, as Harry's connection to Lord Death could be unpredictable. With Ron and Hermione, they might be in awe at first. Ron might be a bit more jealous than in the original story, while Hermione would be extremely curious and want to research everything about Harry's new identity. Snape would likely be even more hostile, seeing Harry as an even greater threat due to his powerful lineage.

While the idea of Harry Potter being Grindelwald's son is not part of the official lore, in the world of fanfiction, authors can bend the rules.
