I have a LR statistic that I know behaves like:
$$\Lambda_n = \gamma_n + O_p(1),$$
where $\gamma_n$ has asymptotic distribution $\chi^2_k$, $k\geq 1$.
What can I say about the rate of $\Lambda_n$? Is it $O_p(1)$?

Yes. You have convergence in distribution, this implies boundedness in probability, see lemma 5.3 here. (Sorry for the short answer, that's all there is to it).
