corecp-lsphp-compat exists so that `openlitespeed` installs on a CoreCP node
without pulling LiteSpeed's own lsphp packages, which depend on a library
Ubuntu 26.04 no longer ships (libenchant-2-2; bug-1031).

The PHP a CoreCP node serves with is corecp-lsphp<XY> in /opt/corecp/lsphp/<XY>,
selected per site by corectl. Nothing on this node runs /usr/local/lsws/lsphp*.

Remove this package only together with the litespeed webserver provider:
without it, apt will try to satisfy openlitespeed with the vendor's lsphp again.
