The answer is fundamentally no — not because there's never been a site that's tried to do something like this, but because when you're at the nit-picky level, the huge amount of variation from lens to lens makes any such site which does not test hundreds of lenses misleading at best — and at the practical level, the difference between these low-cost lenses is really insignificant. Use them with appropriate light and don't stress them out with bright light sources in the frame or intense contrast, and all modern lenses are all quite good.
If you're looking to decide between two lenses with very different functionality (say, widely different focal length), you don't need to compare images of the same scene, so I'm assuming that you're looking to choose between two similar lenses. For that, I recommend reading as many different reviews as you can find, and looking through sample pictures for similar situations, particularly ones which match the shooting you're doing. (Take a look at What image-quality characteristics make a lens good or bad? for some advice on particular things to look for and when they might show up.) Again keep in mind that sample results will vary, so the more different sources, the better.
If you can, it's also nice to actually use a particular lens to see if it meets what you're looking for. I haven't tried it, but I find LensRentals's Keeper program appealing — you start by renting, and then if you like it, you pay a market-reasonable amount to keep it. That way, you can do your own comparison for what really matters to you, and you're testing what you'll actually get, not looking at a sample which may be from an outlier.
