I disagree.
$40 for a set of caster bushes. Do that first then see what happens. It's a lot less stuffing around that doing struts.
I would seriously doubt your struts are bent. Unless it's been whacked against a gutter struts don't just bend! If they are, straighten them! Get someone with a press, work out which way they're bent and straighten them out.
Struts for Dattos are getting too rare to just chuck em out based on suspicion!

To answer your question, yes, it will make the car pull right. Think of my basic analogy from earlier that the wheel coming back (due to stuffed bush) makes that side of the car shorter in effect, causing it to pull right.
