To get a warrant, there has to be a clearly defined crime or potential for a specific crime and some level of probable cause to justify the warrant for Stark's arrest. That can't happen off the bat for one very good reason; we actually have a clear criminal, and an intelligent one, in this case Ultron. Ultron doesn't have clear origins as far as the world is concerned; all they know is that he is somehow related to the Avengers.
Here's where things get murky in regards to actually arresting Stark. Stark did not kill anyone himself nor did he conspire to, and the crime here is mass murder beyond the shadow of a doubt. You cannot arrest Stark for this crime because Stark did not commit it, Ultron did.
What they CAN get a warrant for is seisure of Stark's assets and records, after which an investigation would take place into what happened. That where the part about Ultron being a life form comes into play, because it doesn't matter that the circumstances behind Ultron's creation were born of a mistake on Stark's part, because by the time Ultron caused damage, he was a sentient being completely independant of Stark, and one that knew what he was doing.
In other words, because the crime is clearly defined as mass murder and destruction before they even have a chance to look at Stark, there would have to be some sort of probable cause regard conspiracy on the part of Stark himself for an arrest warrant, which considering Stark was present in the battle to stop Ultron, there isn't.
In other words, to get a warrant for Stark's arrest, you need to first try to redefine the nature of the committed crime to manslaughter, and to do so, you need to make the claim that Ultron is merely a machine operating on cold logic dictated by Stark, which all circumstances by that point imply differently.
