No, I highly doubt they would give a shit about his daughter anymore. They might do something for a fee.
I think he is still very respected, and he died in prison under the toughest circumstances. Plenty of people still around remember that. I just doubt they could do much these days. If they told a guy to leave her alone, he'd call the FBI and say he is being threatened by the Mafia. He'd be portrayed as an innocent victim, and whoever tried to help would go to prison.
