Bias cuts would make it worse. On a bias-cut square, the lengthwise grain and crosswise grains would still be there, but would be running corner-to-corner and bias cuts are so stretchy they are likely to distort even more with handling.
If you think about it, pre-cut squares are probably not going to be cut on the absolute straight-of-grain anyway.
There's no way to cut a piece of fabric without the two grains in there!
