The formation and properties of hadrons, particularly those involving heavyquarks, remain a central topic in particle physics due to the nonperturbativenature of Quantum Chromodynamics (QCD) at low energies. Heavy-quark symmetry(HQS) provides a valuable framework for understanding the behavior of heavyquarks in hadronic systems, offering insights into spin and flavor symmetries.However, discrepancies between HQS predictions and experimental observations --particularly the absence of predicted $B^{(*)}K$ molecular states, which shouldbe the bottom counterparts of the observed $D^{(*)}K$ molecular states --challenge its universality. This study investigates the production of the$\bar{B}_{s0}^{*}(5725)$ and $\bar{B}_{s1}^{*}(5778)$ states, the antiparticlesof the $B_{s0}^{*}(5725)$ and $B_{s1}^{*}(5778)$ states, interpreted asmolecular states containing $B\bar{K}$ and $B^{*}\bar{K}$ components, throughthe reactions $K^{-}p \to \Lambda_{b}^{0}\bar{B}_{s0}^{*}$ and $K^{-}p \to\Lambda_{b}^{0}\bar{B}_{s1}^{*}$. Using effective Lagrangians, we analyze thecross sections, incorporating $t$-channel $B^{(*)}$ meson exchanges andinitial-state $\bar{K}N$ interactions (ISI). Our results reveal significant ISIenhancements and energy-dependent production thresholds, with$\bar{B}_{s0}^{*}(5725)$ exhibiting higher cross sections than$\bar{B}_{s1}^{*}(5778)$. We suggest that the $\bar{B}_{s0}^{*}(5725)$ statecan be optimally searched for at beam energies around $12.91~\text{GeV}$, whilethe $\bar{B}_{s1}^{*}(5778)$ state requires significantly higher energies forits production. These findings provide valuable guidance for experimentalsearches at facilities like CERN and J-PARC, offering a pathway to test HQS andexplore the nature of exotic hadrons. Theoretical uncertainties andimplications for molecular versus conventional quark-antiquark interpretationsare also discussed.
