it's really hard to judge because depending on what the app does it could be reasonable or total slop.
i'm working on a fairly complex application and it's not even near 200k loc. but this is the second version - the first was vibe coded and was over 400k and full of bugs/issues that were slowing down development. i rewrote it and it's half the size, half the dependencies, and much faster & more robust.
is it more complex than your app? hard to say since neither of us want to disclose our identities :)
