You're both right, but talking past each other. You're right that shared dependencies create a problem, but it can be the problem without semantically redefining the services themselves as a shared monolith. Imagine someone came to you with a similar problem and you concluded "distributed monolith", which may lead them to believe that their services should be merged into a single monolith. What if they then told you that it's going to be tough because these were truly separate apps, but that used the same OS wide Python install, one ran on Django/Postgres, another on Flask/SQLite, and another was on Fastapi/Mongo, but they all relied on some of the same underlying libs that are frequently updated. The more accurate finger should point to bad dependency management and you'd tell them about virtualenv or docker.
