Aqui tens o teu CSS atualizado. Para garantir que nada do que já tinhas se altera nos computadores/tablets, o comportamento para mobile foi isolado dentro de uma regra `@media (max-width: 767px)`.

Desta forma, quando o ecrã for inferior a 768px (mobile), a imagem grande desaparece e o carrossel do Elementor volta a assumir o seu comportamento e design padrão (com as setas no sítio original e sem os posicionamentos absolutos forçados).
