I believe this is non issue, you place captcha to make bypassing it much more costly and less profitable to abuse.

LLM models are much harder to drive than any website to serve, so you do not expect mob of bots.

Also keep in mind that this no interaction captchas use behavioral data that are collected in background. Plus you usually have sensitivity levels configured. depending on your use case you might want user proof not being a bot or it might be good enough to just not provide evidence for being one.

bypassing this no interaction captcha can be also purchased as a service, they basically (AFAIK) reuse someone else session for captcha bypass.
