Because there was no need to. In the WN Yuuki had Velda's brainwashing power (used it against Hinata to turn her emotionally detached and apathic) and stole the coffin of the Hero successfully and successfully turned Chloe into a 3-wishes-granting pseudo-djinn who has to fulfill 3 wishes by Yuuki until she is freed. Rimuru tells Leon about that and Leon tries to rescue Chloe somehow by killing Yuuki before he can hand out an order.

In the LN Yuuki doesn't have Velda's powers and sends Laplace for the coffin, however Hinata in this version made a deal with Ruminas and was therefore guarding the coffin herself, hence Laplace had to retreat and later attempts failed until Yuuki did something reckless and unleashed "Manas:Chronoah" by accident who was about to murder everyone, but Rimuru intervened and calmed her down so that she gives control over the body back to Chloe. So Chloe was saved right then and there, so for Leon... there was no reason to go after Yuuki at this point, so he didn't. Then Guy wanted to sell a favor to Rimuru by catching Yuuki for Rimuru, but changed his mind because Yuuki seemed like a very useful pawn and made him his spy within the eastern empire instead.
