Can a kidney infection or UTI cause ovulation tests to come out positive everyday or close to it?

"False positives"? One should always read the directions and information on interpretation of results and/or look for a link to a site for customer service. Repeated positive results should not be related to an infection. I will share this with rei subspecialists also.
No. Interesting question for sure, but not really. Those tests are 'positive every day' for many patients in my practice so i don't rely on them; it's not always clear why, but most either aberrant ovulations or an occasional bad test kit. For certain ovulation does not happen every day: remember the tests don't measure or even predict ovulation, they measure lh concentrations in urine.
