Results on the transverse spherocity dependence of light-flavor particleproduction ($\pi$, K, p, $\phi$, ${\rm K^{*0}}$, ${\rm K}^{0}_{\rm{S}}$,$\Lambda$, $\Xi$) at midrapidity in high-multiplicity pp collisions at$\sqrt{s} = 13$ TeV were obtained with the ALICE apparatus. The transversespherocity estimator ($S_{{\rm O}}^{{\it p}_{\rm T}=1}$) categorizes events bytheir azimuthal topology. Utilizing narrow selections on $S_{\text{O}}^{{\itp}_{\rm T}=1}$, it is possible to contrast particle production in collisionsdominated by many soft initial interactions with that observed in collisionsdominated by one or more hard scatterings. Results are reported for twomultiplicity estimators covering different pseudorapidity regions. The $S_{{\rmO}}^{{\it p}_{\rm T}=1}$ estimator is found to effectively constrain thehardness of the events when the midrapidity ($\left | \eta \right |< 0.8$)estimator is used. The production rates of strange particles are found to beslightly higher for soft isotropic topologies, and severely suppressed in hardjet-like topologies. These effects are more pronounced for hadrons with largermass and strangeness content, and observed when the topological selection isdone within a narrow multiplicity interval. This demonstrates that an importantaspect of the universal scaling of strangeness enhancement with final-statemultiplicity is that high-multiplicity collisions are dominated by soft,isotropic processes. On the contrary, strangeness production in events withjet-like processes is significantly reduced. The results presented in thisarticle are compared with several QCD-inspired Monte Carlo event generators.Models that incorporate a two-component phenomenology, either throughmechanisms accounting for string density, or thermal production, are able todescribe the observed strangeness enhancement as a function of $S_{{\rmO}}^{{\it p}_{\rm T}=1}$.
