The EX 4650 does indeed do 25G.

Good luck with tunnelling LACP, no matter what boxes you have - LACP has (de facto) hard jitter requirements of under 1msec, or you'll be getting TCP resets coming out your ears due to mis-ordered packets.

For your requirements, although I hesitate to recommend them for enterprise/carrier use, Miktotik's EoIP protocol does a much better job of this than most "carrier-grade" implementations.

Otherwise, Juniper and Arista both come to mind, Juniper has the EX4650 that matches your h/w specs, and Arista has, oh, at least half a dozen boxes of various spec that comply, too.  Not 100% sure the Juniper EX does 25G, now that I think of it.
