Looker Studio is great for handling percent fields, but you must know how it works and which options to use. We will see how to indicate to Looker Studio that a field is a percentage and the options to format it.

Use the percentage format for a metric:

Each metric has a predefined format. You can change this format for a metric in a chart or across the entire report.

For only a chart:

Select a chart, and click on the option for a metric:

Edit the options for a metric.

Under Data Type, select Number -> Percent.

Select Data Type percent for a metric.

Then, under Display Format, select the format you want or create one (if you wish to 2 decimals, take Percent(2).

Change the Display Format.

Click Apply and wait for the chart to reload.

Here is the result:
