Issue Reference this PR resolves

#7492

Description of Changes Made (if issue reference is not provided)

Always include explicit ESCAPE '\' clause when doing a ILIKE.

From https://duckdb.org/docs/current/sql/functions/pattern_matching#like

To search within a string for a character that is a wildcard (% or _), the pattern must use an ESCAPE clause and an escape character to indicate the wildcard should be treated as a literal character instead of a wildcard.
