Abstract: In this paper, we investigate the propagation of chaos for solutions to the Liouville equation derived from the Linear-Formation particle model. By imposing certain conditions, we derive the rate of convergence between the $k$-tensor product $f_{t}^{\otimes k}$ of the solution to be Linear-Formation kinetic equation and the $k$-marginal $f_{N,k}^{t}$ of the solution to the Liouville equation corresponding to the Linear-Formation particle model. Specifically, the following estimate holds in terms of $p$-Wasserstein ($1 \leqslant p <\infty$) distance $$ W^p_p(f_{t}^{\otimes k},f_{N,k}^{t}) \leqslant C_{1} \frac{k}{N^{\min(p/2,1)}}\left(1+t^{p}\right){\rm e}^{C_{2}t}, \quad 1\leqslant k\leqslant N. $$

Key words: $p$-Wasserstein distance, Linear-Formation model, mean-field limit, propagation of chaos
