Sounds like a problem created entirely by your legal team, not software or licenses.

Working with legal is advisable instead of ignoring it.

The solution to "colleague got it wrong" is not "silently ignore them" and I never suggested that. In fact my suggestion is precisely that you "work with them" and have them review this specific case.

"Don't use AGPL" is a good baseline rule if you don't have a legal team but does not apply in this case as I'm sure they'd advise if they reviewed it.

You should consider a replacement of your legal team.
