It's "the Service" with capital S, indicating that it is a term specifically defined in the contract. Here "the Service" is defined as "the meet.jit.si service, including related software applications". If that's not vague enough, article 2 gives 8x8 the right to change, modify, etc. the Service at any time without any notice.
The guys at 8x8 may be well intentioned, but their lawyers have done their best to not give the customer any basis to sue the company in any foreseeable circumstances. That is what company lawyers do, for better or worse.
Regardless, it appears that at present time jitsi is not including AI training in their service, and there is no explicit carve-out in their terms for AI training. However, by article 2 they do have the right to store user content, which might become a problem in the future.
