The kagome metals AV<sub>3</sub>Sb<sub>5</sub> (A = K, Rb, Cs) exhibit coexisting correlated phases like charge order and superconductivity. This study compares magneto-chiral transport in CsV<sub>3</sub>Sb<sub>5</sub> and KV<sub>3</sub>Sb<sub>5</sub>. Despite similar electronic structures, KV<sub>3</sub>Sb<sub>5</sub> shows negligible field-switchable electric magneto-chiral anisotropy (eMChA), unlike CsV<sub>3</sub>Sb<sub>5</sub>. This difference suggests that eMChA originates from correlated states, highlighting the importance of environmental interactions.
