Elrond and Sauron, a personal vendetta?

Exactly. Elrond was not a vengeful type at all. Instead, he is described as "kind as summer". Not that he was kind to Sauron or to orcs, but at least after the departure of Celebrian he didn't spend his life hunting orcs as his more vengeful sons did.

Also consider Elrond's early experiences. It were the sons of Feanor, not Sauron, who caused the ruin of his family and his people, who killed his grandfather Dior. Elrond's two uncles Elured and Elurin were left to die in the wilderness by the servants of Celegorm - a terrible crime. it was because of Maedros and Maglor that Elrond lost his mother Elwing. Yet Elrond came to like Maglor when the latter had repented. He has never persecuted the followers of the Feanorings, instead he led the relief force when Sauron attacked Ost-in-Edhil where Celebrimbor son of Curufin and most of the remaining Noldor dwelt.

Now Galadriel had a different temperament, moreover she had dealt with Sauron-Annatar in person. Think how galling it must have been for her to recall the time in Eregion. The very same being who had killed her brother so cruelly was there before her very eyes smiling and showing her deference (and laughing inwardly, no doubt) - and she was unable to stop him from ensnaring and ruining the Mirdain, including her friend and admirer Celebrimbor... Remember how Celebrimbor died? And then Gil-Galad, who was no kin to Elrond, but who was close kin to Galadriel (the grandson of Galadriel's brother Angrod). And then her only daughter tortured by orcs...
I won't be surprised if Galadriel's hate for Sauron has become very personal after all this. Likely he was ever on her mind.

I say to you, Frodo, that even as I speak to you, I perceive the Dark Lord and know his mind, or all of his mind that concerns the Elves. And he gropes ever to see me and my thought. But still the door is closed! '- the Mirror of Galadriel
