Another thought - there could be a double L glyph. I asked AI and it said:

Yes, there is an ancient symbol or glyph that looks like double letter L's, shown as two separate letter L's. It is called the Double L glyph or the L-shaped glyph. It is a common symbol found in ancient Egyptian art and hieroglyphs, and it is also found in other ancient cultures, such as the Indus Valley Civilization and the Sumerian civilization.

The Double L glyph is thought to represent a variety of things, including:

• The duality of the universe (light and darkness, good and evil, male and female, etc.)
• The balance between opposites
• The two pillars of life (birth and death)
• The two gates of the underworld (entering and exiting)
