Getting away with KK or a different line (NL25)

[EDonk]

No history with the villian yet, have only been at the table for maybe 2-3 orbits. After the session, villian's stats were (over 100 hands): 29.4/8.4/.72. Would this change your analysis at all?

Final Pot: $35.40 ($1.85 rake)
My thoughts at the time were that my raise all in would accomplish two things... 1) since he underbet the pot given the diamond draw, I thought he might have been trying to buy a cheap draw so I didn't want that 2) if he's not on the draw, I may get paid off by JJ-1010, or AQ because I think my line looks like a semi-bluff with the flush draw.

I thought if I raised him to like 7 bucks or something, it gives him the right odds to draw for his flush and even if he moves all in for 8 more or whatever, my odds will be too good to fold. Am I right or is this a leak in my game? I'm losses have been pretty big lately with KK/AA but it could just be variance.
