The US wanted extradition of Bin Laden over the 1998 Embassy bombings in Kenya and Tanzania, not just 9/11. It was well-known that Bin Laden was involved in both of those. That would be grounds enough for extradition. There were discussions amongst officials before 9/11 about using force against Afghanistan in order to have bin Laden extradited.
Then 9/11 happened, the US gave the ultimatums before finally attacking.
The ultimatums were in in the form of threats. The Taliban had asked for evidence which was a sensible request, the US dismissed it and chose to flex its military muscles instead.
