It is possible to find recurrences based on a given generating function rather than elements of a sequence.
Since g.f. completely defines the sequence, it would be possible to produce a proof for the recurrences.
Is there any package for such computations?
As of gfun, if it uses only a limited amount of sequence's elements (as you said), it cannot give us any proof.
