No proof it was a false flag. This is nonsense, and worse, it is despicable, insensitive nonsense. Lashkar e Toiba is a Pakistani terrorist group. Ajmal Kasab (one of the terrorists in the 2008 Mumbai attacks) had a relative who fought in the Afghanistan as a Mujahideen, and he was trained in similar camps in Pakistan. Bin Laden was found near a Pakistani military academy. David Headley claimed the Pakistani intelligence agency was involved in the Mumbai attacks. The attack in Pahalgam was evidently done by Pakistan, as it doesn't fit the pattern of indigenous Kashmiri militants. Even in the height of militancy, tourists were not targeted as it alienated the business class and local Kashmiris reliant on tourism. This was an implicit agreement. What's more, Kashmiris came out in huge numbers condemning terrorism for the first time on the streets. You show your ignorance again.

India claims to have hit terrorist bases. Pakistani media has already started spreading fake news. It's best to wait it out as propaganda and emotionally charged lies meant to provoke both sides will start pouring in. So stop spreading lies.
