In my opinion there's no such thing really as an open relationship, I call it 'being single and wanting to have sex with a bunch of people'.
An open relationship is not the same as being single and sleeping with people. People in an open relationship are emotionally committed to one person. They have the freedom to fool around sexually with other people, but they only actually love their partner.

I have a friend right now though and she's going out with two guys and a girl.
If your friend is dating two guys and a girl, that doesn't necessarily mean she's in an open relationship.
Most people in open relationships only say they are dating one person; they only call that one person their boyfriend or girlfriend. Everyone else is usually a "one night stand", "just a friend", or something else casual.
When a group of people are all in a relationship together, that is something different. That is called polyamory. Some people have open polyamorous relationships, but not all do. Some polyamorous people are both physically and emotionally committed to the people in their relationship and do not fool around with anyone outside the relationship.
There are also relationships where a man is a completely faithful to a woman, but the woman can have as many sexual partners as she wants. That is called cuckolding.
And those are just a few simplified examples of the different types of relationships that people can have.

She enjoys it but I really doubt it'll turn into anything serious with any of them. It's long term relationship suicide and in my opinion simply a waste of time.
There are many different people and many different relationships. Just because something doesn't interest you, that doesn't make it wrong, bad, or a waste of time. If your friend is happy, healthy, and consenting and everyone else in the relationship is happy, healthy, and consenting, then you should be supportive.
