We provide an algorithm to decide whether a class of finite graphs that has bounded linear clique width is well-quasi-ordered by the induced subgraph relation in the presence of a labelling of the vertices, where the class is given by an $\mathsf{MSO}$-transduction from finite words. This study leverages tools from automata theory, and the proof scheme allows to derive a weak version of the Pouzet conjecture for classes of bounded linear clique-width. We also provide an automata based characterization of which classes of $\mathsf{NLC}$ graphs are labelled-well-quasi-ordered by the induced subgraph relation, where we recover the results of Daligault Rao and Thomass\'e by encoding the models into trees with the gap embedding relation of Dershowitz and Tzameret.
