How much can I contribute to employees' LPFSAs?

You can match employee's Limited Purpose FSA contributions from $0 up to the maximum of $2750 (2020 annual limit). Since you can't predict ahead of time what employees elect, if any individual employee sets contribution amounts less than yours, Zenefits simply reduces your contribution to match theirs. 

If the LPFSA is a shortened plan year then the maximum contribution and matching amount will be prorated. So if the company is enrolled in the LPFSA effective 7/1 through 12 /31, the employee would only be able to contribute half of the maximum amount, which would be $1375 for 2020. This would then be the maximum that the employer is able to match.
