Actually the education system in Spain enforces an obligatory second language, which is english in 90% of the cases. So yeah, quite a bit of the spanish people do speak english, at varying levels, of course. However in LoL most players should be young and frequent internet users, so I believe it will be pretty rare to see non english-speaking spanish people. Lazy spanish people are the ones that speak just in spanish. Or maybe they are just bad at the language, in that case there is not much point in calling them for speaking in their own language.

In my experience, I can tell spanish from english people just by asking where are they from or, if they are duoing, from them speaking to each other since almost everyone speaks english.

Actually, it might be a cool initiative to have a small glossary of common things you need to say in chat in different languages. Nothing too exciting, maybe stuff like "Group and push" or "Play passive and farm". Off topic, one thing we spanish people are actually pretty gulty at is at swearing. We do it quite a bit more than in most other countries (Ocelote being an extreme example, but one recognizable too).
