Did you not offer to rewrite it in Python? I was a techical director at a company where we worked a lot with frontend contractors. Some loved typescript others were fans of vanilla js. When the balanced tipped there were rewrites from one to the other (ts to js to ts again), the first one two months full time, the second was interspersed with feature development. Of course the developers were very happy they could do it; it improved the solutions and afterward they both had 1) extreme product ownership 2) excellent company problem domain knowledge. So, a win-win for everyone. So I think, especially as it is a smaller part, than translating back in to Python would be warranted (provided you like it and would stay a while), not a big deal and a quite natural option.
