Am I allowed to create a web crawler that collects info from Game Info?

So, I created this little script in python that selects random champions (based on role), but it (obviously) needs a list of all current champions, which can easily be copied by hand - it just takes a while, so I wondered if it was allowed to create a web crawler that looks through the http://gameinfo.euw.leagueoflegends.com/en/game-info/ website and automaticly copies the data. I couldn't find anything about the subject in the terms of use, which is why I ask it on the forums; I want to make sure I don't get in trouble if I do so.

a web crawler is a program/script that surfs the web automaticly.
