Seaborn doesn't seem to have such a function. However, you can use plt.fill_between:

import pandas as pd
import seaborn as sns
import matplotlib.pyplot as plt

df = pd.DataFrame([[0, 0], [1, 1], [2, 0]], columns=['x', 'y'])

fig, ax = plt.subplots()
sns.lineplot(x=df['x'], y=df['y'], ax=ax)
ax.fill_between(df['x'], df['y'], alpha=0.2)
plt.show()

It produces the following:
