OpenBTS won't work without a RX/TX setup obviously ...
(You can extract the RX code and try to run it separatly but that's
not out of the box stuff)

Transmitting without authorization in licensed bands, I'm sure it's
illegal in nearly all countries.
For reception only tough I think it depends on where you are. In
belgium, in all the legislation I read, it's not illegal to receive
only. (Of course, targeting other people conversation and/or
deciphering other things than your own is illegal, but that's covered
by 'privacy/wiretapping' laws rather than purely radiotelecom ones)

You can get experimental low power licences relatively cheaply in some
countries.
(Here in belgium you'll have to go through a company that must have
some telecom related business but that's not hard to do)
Also you can skip the 'air' step with a big attenuator in the middle
works just great. i.e. Connect the BTS output directly to the USRP via
an attenuator. (DO NOT forget the attenuator or your usrp will be
short lived !)

I think airprobe just require code hacking anyway :)

airprobe currently uses a 'standard' gnuradio graph. The only USRP1
specific block is the signal source, just remove it and instanciate a
USRP2 rx block in the python code and it shoudl work fine, pretty easy
to do.
