Nah. It's all down to SE. Personally I think some problems set into the IP before FFXIII.
Do I think SE made mistakes with the release of the title associated with 360? Sure, but the problem was SEs. They should have either made the decision to support 360 earlier and got out a better port or stuck to PS3 only.
I doubt the design would have been that different though. My impression is the design was well locked in when they decided to port to 360. The port itself while decent is weaker in many regards in line with a rapid porting of a mostly finished game.
What they could have done was either got it out earlier on PS3 and not taken the negative hit for delaying to port or got it out on 360 in better shape and avoided the poorer port accusations.
Both those are fairly minor points though. I think the design of the game and its execution is what gathered the negative image and I don't believe the 360 overly influenced that.
Try to be reasonable... its easier than you think...
