The obliquity of Mars has gone through huge changes over the last few billion years, occasionally changing rapidly, occasionally remaining stable. That's the nature of chaos.

Venus also isn't tidally locked per se, but essentially it is. The rotation of Venus is rather bizarre. The solid part of the planet rotates retrograde at a very slow rate. On the other hand, the upper parts of Venus' thick atmosphere rotate prograde. The combined rotation represents one of the four final states in which Venus as a whole can rotate (multiple articles by Laskar, and by others). Venys is in its final rotational state.

The Earth is a marked exception amongst the rocky planets. The key to that marked exception is our exceptionally massive moon. The Earth's moon acts to stabilize the Earth's rotation. Whatever obliquity the proto-Earth had prior to the giant impact is long lost. On the other hand, the obliquity after that giant impact has remained fairly constant thanks to that stabilizing influence.
