I am neither a lawyer nor a DPO, I just worked on GDPR compliance in the past, so take what I say with a grain of salt.
I went and reread parts of GDPR, and I think you are right, though not because of Article 26. I think it's pretty clear that after your ingestion the data has been in good faith anonymized to the degree that it is no longer personal, and therefore your analytics code should be exempt from consent rules.
The interesting question to me is whether a controller deciding to put your pixel on a page for analytics purposes counts as you processing on the controller's behalf to an extent requiring consent. I don't see any clause specifically regarding third party access to personal data (as opposed to third parties processing personal data), so I agree with your stance that it's most likely fine.
