What liability? 8-)
Seriously, if the customer is only multi-homing with you, then there
no big difference between you annoucing a route for them and you're
announcing a route heard from them. In both cases it shows up with
an origin of your AS and in both cases you could have it vanish into
an aggregate route for your ISP.
Our general policy is that if the customer can qualify for their own
AS, they should get one, otherwise we do it with a private AS. There's
really no hassle in getting an AS number, you just need to be able to
say you're multi-homing with two different ISP's. Usually, it comes
down to a don't want to spend money issue. 8-(
