sssd is setting SYSLOG_IDENTIFIER to the debug_prg_name internal var, which is set via calls to server_setup(), and in focal (and probably earlier) that's set to a name like "sssd[sudo]". However the syslog MSG section TAG field format requires only alphanumeric characters:
https://tools.ietf.org/html/rfc3164#section-4.1.3

therefore, providing an identifier of "sssd[sudo]" results in the TAG field (indicating the process name) to be "sssd" and "[sudo]" is the start of the CONTENT field. The convention specified in the RFC states that if the CONTENT field starts with "[PID]:" the value contained inside the brackets may be considered the PID, which is exactly what systemd-journald is doing.
https://tools.ietf.org/html/rfc3164#section-5.3

So, when SYSLOG_IDENTIFIER is set to "sssd[sudo]" that results in a syslog message TAG section that's parsed as having program name 'sssd' and pid 'sudo'.

This is fixed upstream in sssd with commit 00e7b1ada3d1c1071eac79b65c17cd2701c2ae6a, included in groovy and later.
