Just play 2. ... d6.
I just LOVE playing against the London King's Indian. Black holds so many trumps.
For example, you have the option of playing a Panno (a later Nc6 instead of Nbd7) with all of the advantages and none of the risks, since you can meet d5 (attacking the c6-Knight) with ... e5 (counter-attacking the f4-Bishop)... and afterwards meet a Bishop retreat by dropping the Knight back to e7.
Another possibility is to forego ... e5 entirely and (later on) play ... c5 instead, taking advantage of the isolation of White's dark-squared Bishop.
Finally, if you choose to put the b8-Knight on d7 instead of c6, it is sometimes possible to transpose from a London KID into a position that remarkably resembles a Ruy Lopez Breyer variation, but with Black being FOUR MOVES ahead of the usual book lines (because the f8-Bishop arrives on g7 in a single move instead of Bf8-e7-f8-g7 as in the Breyer, and the b8-Knight arrives on d7 in a single move instead of Nb8-c6-b8-d7 as in the Breyer).
I'll sometimes see my opponets (in sub-1200 games) start against an attempted King's Indian Defense with Bishop F4 on MOVE #2. Curious what BLACK's best response would be here:
