Can You Beat Genshin Impact Using Only Layla?!

Of all the support roles in Genshin Impact, shield characters have probably become the most useless ones. Ever since Zhongli came out, shield characters have become very few and far between. The only shield characters that have come out since Zhongli’s release, not including characters that get shields from constellations, are Thoma, Layla, Baizhu, and Kirara. Thoma, Baizhu and Kirara’s shields are not all that good, but they make up for it by having other parts of their kits that make them better. But what about Layla? Well, Layla is one of the only characters with a shield that can hold her own against Zhongli’s shields. Her shield isn’t AS good, but it's still one of the best shields in the game. I’ve already done Zhongli only in the past, so I wonder if Layla can also beat Genshin Impact on her own.
Rules:
I can only use Layla in battle.
Any puzzles that require another element can be completed with another character.
No healing items in battle.
No co-op.
All swords are allowed.
