Well, a prevalent theme is 'redemption'. Kol might be portrayed as a character seeking redemption through his relationship with Bonnie. Also, 'self - discovery' is common. As they interact, both Kol and Bonnie often learn more about themselves. For instance, Bonnie might discover a new side of her power or personality in relation to Kol. And of course, 'love conquers all' is a theme that frequently shows up, emphasizing that their love can overcome any obstacle.
One common theme is the idea of redemption. Kol is often portrayed as a character in need of redemption, and Bonnie can be the one to help him. Another theme is forbidden love. Since they come from different sides in the show's lore, their relationship can be seen as something that is not supposed to happen.
Love and relationship growth is likely to be a common theme.

Power and its implications is another theme. Given their supernatural natures, how they use their powers in relation to their relationship is often written about. For example, Davina's power might be a source of both attraction and danger in their relationship.
Common themes in Harry and Kol fanfiction include the discovery of new powers. Their combined presence might unlock some new, unexpected magical or vampiric abilities. Another is the theme of trust - building. Given their different natures, it takes time for them to trust each other. And there's often a theme of facing a greater threat together.
