Short answer: Yes—you’ll need a paid plan (Starter or higher) to include Eleven Music tracks in a Minecraft mod.
Why:
Free plan: no commercial license and music downloads are not permitted, so you cannot package the audio in a mod. (help.elevenlabs.io)
Paid plans: include a commercial license and allow music downloads (e.g., Starter: up to 30 minutes generated/downloaded per month), with some restrictions (e.g., not for offline TV/film/radio/live ads, no large music libraries for licensing). (elevenlabs.io)
Eleven Music is cleared for broad commercial use (including gaming) across tiers, but for licensing in video games at scale you may need a custom/enterprise arrangement—ElevenLabs directs users to contact Sales for video-game licensing. (elevenlabs.io)
If your mod is non-commercial: the free plan still won’t work because music downloads are disabled on free, so you can’t bundle tracks in the mod. (elevenlabs.io)
