RICO is for charging the boss if you don't have direct evidence against them. In this case they do, so they don't need it.
Also the phrasing here is just wire fraud (18 USC 1343) and conspiracy (18 ISC 371). If they were going towards RICO, you'd expect to see them talking about "patterns of activity", "operating a criminal enterprise" or other phrasing from RICO statues (18 USC 1962).
