"personal data’ means any information relating to an identified or identifiable natural person" - GDPR article 4

Data often pertains to multiple people (trivial case: direct messages between two users); the rights of GDPR apply to your data, regardless of whether it also pertains to multiple others, subject to some restrictions to safeguard the rights of others. Those legal restrictions clearly don't apply because you could pay to obtain that access.

LinkedIn would need to prove in court that the list of users who visited your profile is not your data.

Additionally, your profile is undisputably your data. Per article 15 of the GDPR, you have a right to access "the recipients or categories of recipient to whom the personal data have been or will be disclosed, in particular recipients in third countries or international organisations".
