What is Lee Sin's most reliable build when he mainly has to create a real positional differential?

The most reliable build on Lee Sin is the one that preserves the first spike while still keeping an escape valve. If your item order prevents you from playing the champion's first real window, the build may look strong on paper but it is not reliable.

When should you truly adapt Lee Sin's build instead of simply pushing the standard skirmisher route?

You should adapt as soon as the enemy draft stops you from playing the timing the build was meant to serve. If you need to survive longer, absorb more poke, or answer a specific engage pattern, the purchase order must move before you even think about the final six-slot build.

Which enchant should Lee Sin choose when the real issue is mainly getting out alive after the play?

stasis is often the most stable choice because it directly supports this game plan: create early advantage and convert every kill into map control.
