GDPR, EU. You cannot simply load third party shit on your website, without asking for consent. By downloading an SVG from a third party provider, I would need to ask the visitor, whether transmitting their IP address is OK or not, since that is personal data. Aside form all the information associated with when someone accesses the site.

That's not how the GDPR works at all. If it were, there would be no content distribution networks operating in the EU. Linking to a third party image in document markup does not involve you transmitting anything.
By including external references to third-parties, you’re effectively leaking your visitors’ IP addresses to the third-party. Those IP addresses are considered PII and are covered by the GDPR.
