Without looping it can be achived like below.

private void dgEvents_RowPrePaint(object sender, DataGridViewRowPrePaintEventArgs e)
    {

        FormatRow(dgEvents.Rows[e.RowIndex]);

    }

private void FormatRow(DataGridViewRow myrow)
    {
        try
        {
            if (Convert.ToString(myrow.Cells["LevelDisplayName"].Value) == "Error")
            {
                myrow.DefaultCellStyle.BackColor = Color.Red;
            }
            else if (Convert.ToString(myrow.Cells["LevelDisplayName"].Value) == "Warning")
            {
                myrow.DefaultCellStyle.BackColor = Color.Yellow;
            }
            else if (Convert.ToString(myrow.Cells["LevelDisplayName"].Value) == "Information")
            {
                myrow.DefaultCellStyle.BackColor = Color.LightGreen;
            }
        }
        catch (Exception exception)
        {
            onLogs?.Invoke(exception.Message, EventArgs.Empty);
        }
    }
