Take a look at the proposed duplicate question.  There are other ways of explaining the slow rotation with nearly 180 degree tilt. Capture of a rogue planet is problematic.

This is considered very unlikely. It is actually very difficult for things to be captured into orbits. They pick up speed as they fall in towards the larger object, and that's automatically enough speed to carry them back out. Capture either requires dust and gas to slow the body down, or very lucky gravitational interaction with a third object.

This has happened with moons, but the solar system is much more crowded than the galaxy. For something the size of Venus to pass through the solar system at all would be exceedingly rare.

Finally, it is easy to explain the retrograde rotation by other means. This is where the other question that username_1 mentioned in the comments comes in.
