Loose Flop Call? How much credit to give BDSD?

This is from a post in another forum:

Hero is in EP with Jc Jh.
SB seems to be a straight-forward player.

Preflop: Hero raises, MP calls, LP calls, SB raises. BB folds. Hero calls, MP calls, LP calls.

Flop: Ks Td 6h. Pot = 12.25 small bets

SB bets, Hero ?

You're given 13.25:1 odds on the flop, which justify calling with many draws. Here you have two outs with the Jacks and one OR one and one-half outs with the backdoor straight draw.

With only 3 outs (counting the BDSD as 1 out), you need close to 14:1 odds. But with 3.5 outs you need close to 13:1 odds.

Even if you only count the BDSD as 1 out, should you make a loose flop call here? Would the implied odds make that big a difference to justify the loose call?
