Tight transit in Dallas. Would I be able to do it?

I am flying Finnair middle of September Helsinki to Dallas on Australian passport with only carry-on luggage.

Using Dallas as Transit airport destination for 3 weeks will be Bogota, my partner bought me an AA flexible ticket with only 2.05 hours transit.

I am landing at 3:00pm and departs 5.05PM Anyway to speed my immigration time ?

Skyline is great in Dallas but I think need to change the booking.

These two tickets are from different airlines. How do I handle this ? Just call AA before depart from Hel and organise other flights to get to Bogota or can I wait as the ticket is flexible?
