Somos America, is a non profit group...which kinda begs the question why are they suiing in federal court if they are not 'hurt' by Arpaio's racial profiling?
also, i think Arpaio recently lost the case.

What you're asking about is a term that attorneys call "standing:" that is, you have to be affected by the defendant's acts in order to sue the defendant.
I don't know what Somos America claimed was sufficient to constitute its standing. Its website states that it's an organization "composed of organizations and individuals whose work encompasses issues affecting immigrant communities."
I can theorize several bases on which they could claim standing. Racial profiling causes disproportionate numbers of their members to be arrested, making their work more difficult. That's the first thing that comes to mind.
Standing doesn't require a great deal of harm to be experienced, especially when the plaintiff is seeking injunctive relief.
Thank you for your thoughtful question.

A LOT of different groups like to put their "two-cents" in where
there is a controversial or well known law suit pending. You see
the Small Business Manufacturers and MADD and others do this
all the time. Somos America wants their "views" aired re: "racial
profiling" to be known. That's why.
