While you may be correct that the pillars are not structural in nature you should consider retaining a “structural” engineer who is an APEGA Professional Member (P.Eng. or PL(Eng.)) look at the areas of concern and confirm in writing whether they are or are not structural in nature.
You can confirm the individual who visits the site is a practicing member of APEGA on line at https://www.apega.ca/members/member-directory/
CCI has an engineering directory in their Insight magazine.
